This is where the <strong>VOS3000 position keeper dollar sign<\/strong> ($) becomes indispensable. The dollar sign in a Target Prefix tells VOS3000 to keep and not change the digit at that position from the original number \u2014 essentially &#8220;passing through&#8221; the matched digit unchanged while allowing other transformations around it. \ud83d\udd27<\/p>\n\n\n\n<p>\u2699\ufe0f The VOS3000 2.1.9.07 manual \u00a74.3.1 provides the definitive example: Original Prefix &#8220;0134&#8221;, Target Prefix &#8220;$$$&#8221;, input number &#8220;0134131&#8221; becomes &#8220;013131&#8221;. The three dollar signs in the target prefix retain the last three digits (&#8220;131&#8221;) from the original number while the prefix &#8220;0134&#8221; is replaced. This behavior \u2014 preserving positional digits during transformation \u2014 makes the <strong>VOS3000 position keeper dollar sign<\/strong> one of the most powerful tools for building precise number manipulation rules. \ud83d\udcca<\/p>\n\n\n\n<p>\ud83c\udfaf This guide covers every aspect of the VOS3000 position keeper dollar sign: how it preserves digit positions, practical transformation examples from the manual, how it interacts with wildcards and other dial plan features, and real-world scenarios where positional retention is essential.

According to the VOS3000 manual \u00a74.3.1, &#8220;$ means keep and not change dial plan the position.&#8221; Each dollar sign preserves exactly one digit position, enabling precise number transformation where you remove or modify a prefix while keeping the subsequent digits intact at their exact positions.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"\u2753-how-is-the-dollar-sign-different-from-the-asterisk-in-vos-3000-dial-plans\">\u2753 How is the dollar sign different from the asterisk in VOS3000 dial plans?<\/h3>\n\n\n\n<p>\ud83d\udd27 The dollar sign ($) preserves individual digit positions one at a time, while the asterisk (*) carries forward all matched digits as a group. With &#8220;$$$&#8221;, you preserve exactly three specific digit positions. With &#8220;*&#8221;, you preserve all remaining digits after the target prefix in a single operation. The dollar sign gives you positional precision \u2014 you can choose which positions to keep \u2014 while the asterisk is a bulk preservation of everything matched. Use $ when you know the exact number of digits to preserve, and * when the remaining digit count varies.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"\u2753-can-i-combine-dollar-signs-with-fixed-digits-in-the-target-prefix\">\u2753 Can I combine dollar signs with fixed digits in the Target Prefix?<\/h3>\n\n\n\n<p>|carrier interconnect number formatting per <a href=\"https:\/\/www.itu.int\/rec\/T-REC-E.164\" target=\"_blank\" rel=\"noopener\">ITU-T E.164<\/a> standards<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"\u2753-what-happens-if-i-use-too-many-or-too-few-dollar-signs\">\u2753 What happens if I use too many or too few dollar signs?<\/h3>\n\n\n\n<p>\ud83d\udccb If you use more dollar signs than there are remaining digits after the Original Prefix match, the extra dollar signs may produce unexpected results or be treated as having no corresponding digit to preserve. If you use fewer dollar signs, only the first N digits will be preserved and the rest truncated. Always count the exact number of digits that follow the Original Prefix in your input numbers and use exactly that many dollar signs. For variable-length numbers, consider using the asterisk (*) wildcard instead of the dollar sign.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"\u2753-does-the-dollar-sign-work-in-the-original-prefix-field\">\u2753 Does the dollar sign work in the Original Prefix field?<\/h3>\n\n\n\n<p>\ud83d\udd04 No, the dollar sign position keeper is designed for use in the Target Prefix field only. In the Original Prefix, use exact digits, the asterisk (*) wildcard, or the question mark (?) wildcard for pattern matching. The dollar sign&#8217;s purpose is specifically to preserve digit positions during the transformation output \u2014 it does not have a matching function in the input pattern. The VOS3000 manual \u00a74.3.1 only documents the $ symbol&#8217;s behavior in the Target Prefix context.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"\u2753-how-does-the-position-keeper-interact-with-other-dial-plan-features\">\u2753 How does the position keeper interact with other dial plan features?<\/h3>\n\n\n\n<p>\ud83d\udcca The <strong>VOS3000 position keeper dollar sign<\/strong> works alongside other dial plan features including wildcards (* and ?), escape characters (L\/E\/G\/F), and semicolons. However, mixing $ with ? in the same Target Prefix requires careful attention \u2014 the ? generates a random digit while $ preserves an existing digit. Similarly, using $ within semicolon-separated targets means each target option can independently use dollar signs for positional retention. Always test combined configurations thoroughly to verify the expected transformation behavior.<\/p>\n\n\n\n<p>\ud83d\udcde Still have questions?
