Whether you need to add area codes, strip prefixes, or rewrite entire number sequences, <strong>VOS3000 dial plan wildcards<\/strong> give you the pattern-matching power to do it precisely and efficiently. The two wildcard characters \u2014 asterisk (*) and question mark (?) \u2014 are the foundation of flexible number transformation in VOS3000, and understanding how they work is essential for any VoIP engineer configuring routing rules. \ud83d\udd27<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">\u2699\ufe0f The asterisk wildcard matches any number of digits (including zero), making it ideal for catch-all rules that apply regardless of the dialed number length. The question mark wildcard matches exactly one digit, giving you fine-grained control when you need to match specific number patterns with positional precision. Together, these <strong>VOS3000 dial plan wildcards<\/strong> enable sophisticated number transformation rules that handle national dialing conventions, international prefix manipulation, and gateway-specific number formatting requirements. \ud83d\udcca<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">\ud83c\udfaf This guide covers every aspect of VOS3000 dial plan wildcards: how the asterisk and question mark characters match digits in original prefix patterns, how they interact with target prefix replacement rules, how VOS3000 resolves conflicts between overlapping dial plans using longest-match priority, and practical configuration examples for common VoIP routing scenarios.

The VOS3000 softswitch evaluates incoming call numbers against dial plan rules, and when a match is found, it applies the corresponding Target Prefix transformation. The wildcard characters extend this matching capability beyond exact digit-to-digit comparison, enabling a single dial plan rule to cover an entire range of number patterns. \ud83d\udcde<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">\ud83d\udca1 <strong>Why wildcards matter:<\/strong> Without wildcard matching, you would need to create a separate dial plan rule for every possible number prefix \u2014 an impractical approach when dealing with thousands of area codes, mobile prefixes, or international dialing patterns. Wildcards let you express complex matching logic in a single rule, reducing configuration complexity and making your dial plan table manageable and maintainable.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">\ud83d\udccd <strong>Location in VOS3000 Client:<\/strong> Operation management \u2192 Gateway operation \u2192 Routing gateway \u2192 Dial plan (also available in Mapping gateway and Phone dial plans)<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"\ud83d\udccb-the-two-vos-3000-dial-plan-wildcard-characters\">\ud83d\udccb The Two VOS3000 Dial Plan Wildcards Characters<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">\ud83c\udf10 VOS3000 supports exactly two wildcard characters for pattern matching in dial plans, each with distinct matching behavior:<\/p>\n\n\n\n<figure class=\"wp-block-table\"><table class=\"has-fixed-layout\"><tbody><tr><th class=\"has-text-align-left\" data-align=\"left\">Wildcard<\/th><th class=\"has-text-align-left\" data-align=\"left\">Name<\/th><th class=\"has-text-align-left\" data-align=\"left\">Matching Behavior<\/th><th class=\"has-text-align-left\" data-align=\"left\">Use Case<\/th><\/tr><tr><td>*<\/td><td>Asterisk (star)<\/td><td>Matches any number of digits, including zero digits<\/td><td>Catch-all rules, add\/remove\/replace entire prefixes<\/td><\/tr><tr><td>?<\/td><td>Question mark<\/td><td>Matches exactly one digit (0-9)<\/td><td>Positional matching where a specific digit position is variable<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\">\ud83d\udd11 <strong>Key distinction:<\/strong> The asterisk (*) is greedy \u2014 it consumes as many digits as possible in the match. The question mark (?) is precise \u2014 it matches exactly one digit and no more. You can use multiple question marks in a row (e.g., ???) to match exactly three digits, but you cannot control the specific digit value \u2014 each ? matches any single digit from 0 to 9.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"\u2699\ufe0f-asterisk-wildcard-match-any-number-of-digits\">\u2699\ufe0f Asterisk Wildcard (*) \u2014 Match Any Number of Digits<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">\ud83d\udd27 The asterisk wildcard is the most powerful and most frequently used of the <strong>VOS3000 dial plan wildcards<\/strong>. In the Original Prefix field, the asterisk matches any sequence of digits \u2014 including an empty sequence. This means a dial plan with Original Prefix &#8220;*&#8221; will match every possible dialed number, making it the ultimate catch-all rule.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">According to the official VOS3000 2.1.9.07 manual \u00a74.3.1, the following examples demonstrate asterisk wildcard behavior in dial plans:<\/p>\n\n\n\n<figure class=\"wp-block-table\"><table class=\"has-fixed-layout\"><tbody><tr><th class=\"has-text-align-left\" data-align=\"left\">Original Prefix<\/th><th class=\"has-text-align-left\" data-align=\"left\">Target Prefix<\/th><th class=\"has-text-align-left\" data-align=\"left\">Input Number<\/th><th class=\"has-text-align-left\" data-align=\"left\">Result<\/th><th class=\"has-text-align-left\" data-align=\"left\">Explanation<\/th><\/tr><tr><td>*<\/td><td>025*<\/td><td>117<\/td><td>025117<\/td><td>Add prefix 025 before any number<\/td><\/tr><tr><td>*<\/td><td>(empty)<\/td><td>02584316146<\/td><td>(empty)<\/td><td>Delete entire number<\/td><\/tr><tr><td>*<\/td><td>12345678<\/td><td>02584316146<\/td><td>12345678<\/td><td>Replace entire number with fixed value<\/td><\/tr><tr><td>025*<\/td><td>010<\/td><td>02584316146<\/td><td>010<\/td><td>Replace 025-prefixed number with 010<\/td><\/tr><tr><td>025*<\/td><td>010*<\/td><td>02584316146<\/td><td>01002584316146<\/td><td>Add prefix 010 while keeping 025 prefix<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\">\ud83d\udca1 <strong>How the asterisk preserves digits:<\/strong> When you use the asterisk in both the Original Prefix and Target Prefix, the digits matched by the asterisk in the original number carry through to the target. For example, Original Prefix &#8220;025*&#8221; matches &#8220;02584316146&#8221; where the asterisk matches &#8220;84316146&#8221;. In Target Prefix &#8220;010*&#8221;, the &#8220;010&#8221; is the new prefix and the &#8220;*&#8221; carries forward the matched digits &#8220;84316146&#8221;, producing &#8220;01084316146&#8221;.

Understanding these rules is critical to avoid unexpected number transformations:<\/p>\n\n\n\n<figure class=\"wp-block-table\"><table class=\"has-fixed-layout\"><tbody><tr><th class=\"has-text-align-left\" data-align=\"left\">Rule<\/th><th class=\"has-text-align-left\" data-align=\"left\">Description<\/th><th class=\"has-text-align-left\" data-align=\"left\">Example<\/th><\/tr><tr><td>Longest match wins<\/td><td>When multiple dial plans match, the one with the longest original prefix is selected<\/td><td>&#8220;010&#8221; wins over &#8220;0&#8221; for number 01012345678<\/td><\/tr><tr><td>* has lowest priority<\/td><td>The asterisk wildcard pattern is only matched when no other specific pattern matches<\/td><td>&#8220;025*&#8221; matches only if no more specific &#8220;0258&#8221; rule exists<\/td><\/tr><tr><td>Exact match is highest<\/td><td>An exact prefix without wildcards always takes precedence over wildcard patterns of the same length<\/td><td>&#8220;025&#8221; exact beats &#8220;02?&#8221; wildcard<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\">\ud83d\udd11 <strong>Practical implication:<\/strong> You can safely create a catch-all &#8220;*&#8221; rule as a default transformation while adding more specific rules for particular prefixes. VOS3000 will always prefer the more specific rule. This layered approach is the recommended way to structure your dial plan configuration \u2014 a broad default with narrow exceptions.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"\u2753-question-mark-wildcard-match-exactly-one-digit\">\u2753 Question Mark Wildcard (?) \u2014 Match Exactly One Digit<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">\ud83c\udfaf The question mark wildcard in <strong>VOS3000 dial plan wildcards<\/strong> matches exactly one digit at a specific position. This gives you positional control that the asterisk cannot provide. While the asterisk is broad and greedy, the question mark is narrow and precise \u2014 it matches any single digit from 0 to 9, but only one digit in that exact position.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">According to the VOS3000 manual \u00a74.3.1, the question mark can appear multiple times in a single pattern, and each occurrence matches an independent digit. The following example from the manual illustrates this behavior:<\/p>\n\n\n\n<figure class=\"wp-block-table\"><table class=\"has-fixed-layout\"><tbody><tr><th class=\"has-text-align-left\" data-align=\"left\">Original Prefix<\/th><th class=\"has-text-align-left\" data-align=\"left\">Target Prefix<\/th><th class=\"has-text-align-left\" data-align=\"left\">Input Number<\/th><th class=\"has-text-align-left\" data-align=\"left\">Result<\/th><th class=\"has-text-align-left\" data-align=\"left\">Explanation<\/th><\/tr><tr><td>0??8431<\/td><td>8431<\/td><td>02584316146<\/td><td>84316146<\/td><td>Two ? wildcards match any two digits between 0 and 8431<\/td><\/tr><tr><td>*<\/td><td>12345?78<\/td><td>02584316146<\/td><td>12345178 (or similar)<\/td><td>? in target prefix becomes a random digit<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\">\ud83d\udca1 <strong>Question mark in target prefix:<\/strong> When the question mark appears in the Target Prefix field, it generates a random digit (0-9) at that position. This is different from the Original Prefix usage where it matches an existing digit. This distinction is crucial \u2014 in the original prefix, ? matches any digit; in the target prefix, ? produces a random digit. This feature is documented in \u00a74.3.1 of the VOS3000 manual.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"\ud83d\udccb-common-question-mark-pattern-examples\">\ud83d\udccb Common Question Mark Pattern Examples<\/h3>\n\n\n\n<figure class=\"wp-block-table\"><table class=\"has-fixed-layout\"><tbody><tr><th class=\"has-text-align-left\" data-align=\"left\">Pattern<\/th><th class=\"has-text-align-left\" data-align=\"left\">Matches<\/th><th class=\"has-text-align-left\" data-align=\"left\">Does NOT Match<\/th><th class=\"has-text-align-left\" data-align=\"left\">Scenario<\/th><\/tr><tr><td>0??8431<\/td><td>0258431&#8230;, 0138431&#8230;, 0998431&#8230;<\/td><td>08431&#8230; (only one digit after 0)<\/td><td>Area codes with two-digit variable middle<\/td><\/tr><tr><td>00?<\/td><td>001, 002, 003&#8230; 009<\/td><td>00, 0012 (too many\/few digits)<\/td><td>International prefix with single country digit<\/td><\/tr><tr><td>13???????<\/td><td>1301234567, 1398765432<\/td><td>13, 13012 (too short)<\/td><td>Mobile number pattern with fixed prefix<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"\ud83d\udda5\ufe0f-combined-wildcard-patterns-with-semicolons-and-ranges\">\ud83d\udda5\ufe0f Combined Wildcard Patterns with Semicolons and Ranges<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">\ud83d\udd04 The <strong>VOS3000 dial plan wildcards<\/strong> become even more powerful when combined with semicolon-separated targets and numeric ranges.

The two wildcard characters are the asterisk (*), which matches any number of digits including zero, and the question mark (?), which matches exactly one digit. These wildcards enable you to create flexible number transformation rules that handle a wide range of dialed number patterns without needing a separate rule for each possible number. They are documented in the VOS3000 2.1.9.07 manual \u00a74.3.1.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"\u2753-how-does-the-asterisk-wildcard-work-in-vos-3000-dial-plans\">\u2753 How does the asterisk wildcard work in VOS3000 dial plans?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">\ud83d\udd27 The asterisk (*) in the Original Prefix matches any sequence of digits \u2014 from zero digits to an unlimited number. When used in the Target Prefix, it inserts the digits that were matched by the corresponding asterisk in the Original Prefix. For example, Original Prefix &#8220;025*&#8221; with Target Prefix &#8220;010*&#8221; transforms &#8220;02584316146&#8221; into &#8220;01084316146&#8221; \u2014 the asterisk in the original prefix matches &#8220;84316146&#8221; and the asterisk in the target prefix carries those digits forward after the new &#8220;010&#8221; prefix. This carry-forward behavior is the key to prefix manipulation in VOS3000 dial plans.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"\u2753-how-does-the-question-mark-wildcard-work-in-vos-3000-dial-plans\">\u2753 How does the question mark wildcard work in VOS3000 dial plans?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">\ud83c\udfaf The question mark (?) serves two different purposes depending on where it appears. In the Original Prefix, it matches exactly one digit (0-9) at that position. For example, &#8220;0??8431&#8221; matches any number starting with 0, followed by any two digits, followed by 8431. In the Target Prefix, the question mark generates a random digit (0-9) at that position. This dual behavior is important to understand \u2014 matching in the original prefix versus generating in the target prefix \u2014 as documented in the VOS3000 manual \u00a74.3.1.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"\u2753-what-is-the-priority-of-vos-3000-dial-plan-wildcards\">\u2753 What is the priority of VOS3000 dial plan wildcards?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">\ud83d\udccb VOS3000 uses longest-match priority for dial plan selection. When multiple dial plan rules could match a given number, the rule with the longest original prefix is selected. The asterisk (*) wildcard has the lowest priority and will only be matched when no other more specific pattern matches. This means you can safely create a catch-all &#8220;*&#8221; rule as a default while adding more specific rules like &#8220;025*&#8221; or &#8220;010&#8221; for particular prefixes \u2014 VOS3000 will always prefer the more specific match.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"\u2753-can-i-combine-and-wildcards-in-the-same-dial-plan-rule\">\u2753 Can I combine * and ? wildcards in the same dial plan rule?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">\ud83d\udd04 Yes, you can combine asterisk and question mark wildcards in the same dial plan rule&#8217;s Original Prefix. For example, &#8220;0??*&#8221; would match numbers starting with 0, followed by any two digits, followed by any number of additional digits. However, combining wildcards in the Target Prefix requires careful attention \u2014 the asterisk carries matched digits forward while the question mark generates random digits. Understanding the interaction between these two behaviors is essential for correct number transformation.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"\u2753-how-do-vos-3000-dial-plan-wildcards-interact-with-semicolons-and-ranges\">\u2753 How do VOS3000 dial plan wildcards interact with semicolons and ranges?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">\ud83d\udcca The VOS3000 dial plan wildcards work together with semicolons and ranges in the Target Prefix field. Semicolons (;) separate multiple substitution targets \u2014 VOS3000 randomly selects one target at call time. Ranges (e.g., 8008100-8008121) define a span of numbers from which one is randomly selected. You can combine these with wildcards: for example, Target Prefix &#8220;12345678;8008100-8008121;12345?78&#8221; would randomly choose between three different transformation patterns for each call. This is documented in \u00a74.3.1 of the VOS3000 manual.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">\ud83d\udcde Still have questions?
