By comparing performance metrics across multiple gateways over the same period, operators can objectively rank their carriers:<\/p>\n\n\n\n<figure class=\"wp-block-table is-style-stripes\"><table class=\"has-fixed-layout\"><tbody><tr><th class=\"has-text-align-left\" data-align=\"left\">Carrier<\/th><th class=\"has-text-align-left\" data-align=\"left\">ASR<\/th><th class=\"has-text-align-left\" data-align=\"left\">ACD<\/th><th class=\"has-text-align-left\" data-align=\"left\">PDD<\/th><th class=\"has-text-align-left\" data-align=\"left\">Score<\/th><\/tr><tr><td>\ud83d\udce1 Carrier A<\/td><td>62%<\/td><td>4.2 min<\/td><td>3.1 sec<\/td><td>\u2b50\u2b50\u2b50\u2b50\u2b50<\/td><\/tr><tr><td>\ud83d\udce1 Carrier B<\/td><td>48%<\/td><td>3.8 min<\/td><td>5.4 sec<\/td><td>\u2b50\u2b50\u2b50\u2b50<\/td><\/tr><tr><td>\ud83d\udce1 Carrier C<\/td><td>31%<\/td><td>2.1 min<\/td><td>8.9 sec<\/td><td>\u2b50\u2b50<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"\ud83d\udd04-using-historical-performance-for-route-optimization\">\ud83d\udd04 Using VOS3000 Historical Performance for Route Optimization<\/h2>\n\n\n\n<p>\ud83d\udce1 The primary business application of VOS3000 historical performance analysis is route optimization through evidence-based carrier management. By tracking ASR, ACD, and PDD trends for each termination gateway over time, operators can make informed decisions about traffic allocation. When a carrier&#8217;s ASR shows a consistent downward trend over two or more weeks, this signals a quality degradation that warrants investigation and potentially reducing traffic allocation to that route. <\/p>\n\n\n\n<p>Conversely, carriers with improving or stable high ASR should receive increased traffic allocation to maximize call completion rates and revenue. The historical performance data transforms carrier management from a reactive process (waiting for customer complaints) to a proactive one (detecting quality changes before they impact customers). \ud83d\udcc8<\/p>\n\n\n\n<p>\ud83d\udcca <strong>Route optimization decision framework using historical performance:<\/strong><\/p>\n\n\n\n<figure class=\"wp-block-table is-style-stripes\"><table class=\"has-fixed-layout\"><tbody><tr><th class=\"has-text-align-left\" data-align=\"left\">Performance Pattern<\/th><th class=\"has-text-align-left\" data-align=\"left\">Duration<\/th><th class=\"has-text-align-left\" data-align=\"left\">Recommended Action<\/th><\/tr><tr><td>\ud83d\udcc9 ASR drop &gt; 10%<\/td><td>1-2 days<\/td><td>Monitor, investigate root cause<\/td><\/tr><tr><td>\ud83d\udcc9 ASR drop &gt; 15%<\/td><td>3-7 days<\/td><td>Reduce traffic, contact carrier, add backup route<\/td><\/tr><tr><td>\ud83d\udcc8 PDD increase &gt; 30%<\/td><td>1 week+<\/td><td>Investigate network path, consider alternative route<\/td><\/tr><tr><td>\ud83d\udcc9 ACD drop &gt; 20%<\/td><td>2+ weeks<\/td><td>Quality issue \u2014 check for audio problems, route congestion<\/td><\/tr><tr><td>\ud83d\udcc8 ASR consistently high<\/td><td>1 month+<\/td><td>Increase traffic allocation, negotiate better rates<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"\ud83d\udcca-performance-analysis-and-sla-compliance\">\ud83d\udcca Performance Analysis and SLA Compliance<\/h2>\n\n\n\n<p>\u2696\ufe0f For VoIP operators who provide Service Level Agreements (SLAs) to their customers, VOS3000 historical performance analysis is the tool for proving SLA compliance. SLAs typically specify minimum ASR thresholds, maximum PDD limits, and minimum ACD values for different destination categories. By running historical performance analysis for each SLA-covered destination over the contract period, operators can generate objective evidence of whether they met or exceeded the agreed quality standards. <\/p>\n\n\n\n<p>This data is invaluable during SLA review meetings and can prevent unwarranted penalty charges from customers who claim quality was below standards. Operators should establish a regular cadence of SLA reporting \u2014 typically monthly \u2014 using the historical performance analysis module as the data source, supplemented by data from the report management system for financial SLA metrics. \ud83d\udccb<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"\u26a0\ufe0f-interpreting-performance-data-correctly\">\u26a0\ufe0f Interpreting Performance Data Correctly<\/h2>\n\n\n\n<p>\ud83d\udd0d Correct interpretation of VOS3000 historical performance data requires understanding the context behind the numbers. A low ASR does not always indicate a carrier problem \u2014 it may reflect legitimate network conditions in the destination country (such as mobile phone switched off, busy lines, or network congestion during peak hours). Similarly, short ACD values may indicate that callers in certain cultural contexts naturally make shorter calls, not that call quality is poor. PDD values can be affected by the originating network&#8217;s dial plan configuration, not just the terminating carrier&#8217;s performance. <\/p>\n\n\n\n<p>The key to meaningful analysis is comparing performance against your own historical baseline for the same destination, same time period, and same traffic pattern, rather than using generic industry benchmarks. Week-over-week and month-over-month comparisons of the same route provide the most actionable insights. \ud83d\udcca<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"\ud83d\udca1-best-practices-for-historical-performance-analysis\">\ud83d\udca1 Best Practices for Historical Performance Analysis<\/h2>\n\n\n\n<figure class=\"wp-block-table is-style-stripes\"><table class=\"has-fixed-layout\"><tbody><tr><th class=\"has-text-align-left\" data-align=\"left\">Practice<\/th><th class=\"has-text-align-left\" data-align=\"left\">Recommendation<\/th><\/tr><tr><td>\ud83d\udcc5 Weekly Reviews<\/td><td>Run performance analysis every Monday for previous week<\/td><\/tr><tr><td>\ud83c\udf0d By Destination<\/td><td>Analyze top 10 destinations separately \u2014 quality varies by route<\/td><\/tr><tr><td>\ud83d\udcca Set Thresholds<\/td><td>Define minimum ASR\/ACD thresholds per destination<\/td><\/tr><tr><td>\ud83d\udcc8 Track Trends<\/td><td>Focus on week-over-week changes, not absolute values<\/td><\/tr><tr><td>\ud83d\udce7 Share Reports<\/td><td>Send carrier scorecards to vendors monthly<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<p>\ud83d\udcac For performance analysis support, WhatsApp us at <strong>+8801911119966<\/strong>. \ud83d\udcf1<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"\u2753-frequently-asked-questions\">\u2753 Frequently Asked Questions<\/h2>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"\u2753-how-does-vos-3000-calculate-asr-in-historical-performance\">\u2753 How does VOS3000 calculate ASR in historical performance?<\/h3>\n\n\n\n<p>\ud83d\udcde VOS3000 calculates ASR as: (Number of calls with status &#8220;Answered&#8221; \/ Total number of call attempts) \u00d7 100%. Calls with statuses like &#8220;Busy,&#8221; &#8220;No Answer,&#8221; &#8220;Cancel,&#8221; and failed calls are counted in the denominator but not the numerator. This is the industry-standard ASR calculation. The historical performance analysis aggregates this across the selected time period and grouping interval (day\/week\/month). \ud83d\udcca<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"\u2753-what-is-a-good-asr-value-for-international-vo-ip-routes\">\u2753 What is a good ASR value for international VoIP routes?<\/h3>\n\n\n\n<p>\ud83c\udfaf ASR benchmarks vary significantly by destination country and route type. Generally: Premium routes to developed countries (USA, UK, Western Europe) should achieve 50-70% ASR. Routes to developing markets may see 30-50% ASR. CLI routes typically have higher ASR than non-CLI. If ASR drops below 25% consistently, investigate carrier quality or potential fraud. Always compare against your own historical baseline for the same destination rather than generic benchmarks. \ud83d\udcc8<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"\u2753-can-i-set-up-automated-alerts-when-performance-drops\">\u2753 Can I set up automated alerts when performance drops?<\/h3>\n\n\n\n<p>\ud83d\udea8 Yes, VOS3000 provides <a href=\"https:\/\/multahost.com\/blog\/vos3000-mapping-alarm-configuration\/\">mapping and routing alarms<\/a> that can trigger when ASR, ACD, or call rate fall below configured thresholds. These alarms can send email notifications, SMS, or voice alerts. For historical trend-based alerting (e.g., &#8220;alert when ASR drops 10% week-over-week&#8221;), use external monitoring tools that pull data via the <a href=\"https:\/\/multahost.com\/blog\/vos3000-web-api\/\">VOS3000 Web API<\/a>. \ud83d\udcca<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"\u2753-how-far-back-can-i-analyze-historical-performance\">\u2753 How far back can I analyze historical performance?<\/h3>\n\n\n\n<p>\ud83d\udcc5 The analysis range is limited only by your CDR retention policy. Most operators retain 3-12 months of granular CDR data. For longer-term analysis, the <a href=\"https:\/\/multahost.com\/blog\/vos3000-report-management\/\">report management<\/a> scheduled reports can save monthly performance summaries indefinitely. Performance analysis on very large date ranges (6+ months) may take longer to generate. \u23f1\ufe0f<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"\u2753-what-causes-sudden-asr-drops\">\u2753 What causes sudden ASR drops?<\/h3>\n\n\n\n<p>\u26a0\ufe0f Sudden ASR drops can be caused by: (1) Carrier network issues or outages, (2) Route congestion during peak hours, (3) Destination country regulatory blocks, (4) CLI suppression on routes requiring CLI, (5) Fraud attacks generating fake call attempts, (6) Incorrect routing configuration sending calls to wrong gateway. Use the <a href=\"https:\/\/multahost.com\/blog\/vos3000-call-distribution-analysis\/\">call distribution analysis<\/a> combined with gateway fail analysis to identify root causes. \ud83d\udd27<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"\u2753-can-i-compare-multiple-gateways-in-one-analysis\">\u2753 Can I compare multiple gateways in one analysis?<\/h3>\n\n\n\n<p>\ud83d\udcca Yes, the VOS3000 historical performance analysis allows selecting multiple gateways for comparison. The results show performance metrics side-by-side for each gateway, making it easy to identify your best and worst performing carriers. This is the recommended approach for carrier scorecarding and route optimization decisions. \ud83d\udcc8<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"\ud83d\udcca-advanced-historical-performance-analysis-techniques\">\ud83d\udcca Advanced Historical Performance Analysis Techniques<\/h2>\n\n\n\n<p>\ud83d\udd27 Beyond basic ASR\/ACD\/PDD tracking, experienced VOS3000 operators employ several advanced analysis techniques using historical performance data. One powerful technique is &#8220;same-day comparison&#8221; \u2014 running historical performance analysis for the same day of the week across multiple weeks (e.g., comparing all Mondays in a month) to establish a reliable baseline while controlling for day-of-week traffic variations. Another technique is &#8220;gateway pair analysis&#8221; \u2014 comparing two gateways that carry traffic to the same destination to determine which one consistently delivers better quality, enabling evidence-based routing decisions. <\/p>\n\n\n\n<p>A third technique is &#8220;pre\/post change analysis&#8221; \u2014 running historical performance for the period before and after a configuration change (such as a route modification or carrier switch) to objectively measure the impact of the change on call quality metrics. These systematic approaches transform historical performance analysis from a passive reporting tool into an active decision-making framework. \ud83d\udcc8<\/p>\n\n\n\n<p>\ud83d\udcca <strong>Advanced analysis methodology:<\/strong><\/p>\n\n\n\n<ol class=\"wp-block-list\">\n<li>\ud83d\udcc5 <strong>Baseline Establishment:<\/strong> Run 30-day historical performance for each major destination to establish normal ASR\/ACD\/PDD ranges<\/li>\n\n\n\n<li>\ud83d\udcca <strong>Threshold Definition:<\/strong> Set alert thresholds at 2 standard deviations from baseline for each metric<\/li>\n\n\n\n<li>\ud83d\udd0d <strong>Anomaly Detection:<\/strong> Compare current week performance against baseline to identify statistically significant deviations<\/li>\n\n\n\n<li>\ud83d\udce1 <strong>Root Cause Analysis:<\/strong> When anomalies are detected, drill down by gateway and time-of-day to isolate the cause<\/li>\n\n\n\n<li>\ud83d\udd04 <strong>Corrective Action:<\/strong> Adjust routing, contact carriers, or modify configuration based on analysis findings<\/li>\n\n\n\n<li>\ud83d\udcc8 <strong>Verification:<\/strong> Re-run analysis after corrective action to confirm the issue is resolved<\/li>\n<\/ol>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"\u2699\ufe0f-performance-analysis-system-configuration\">\u2699\ufe0f Performance Analysis System Configuration<\/h2>\n\n\n\n<p>\ud83d\udd27 The VOS3000 historical performance analysis module relies on underlying CDR data for its calculations. The accuracy and granularity of the analysis depends on several system configuration factors. The CDR write interval parameter determines how quickly call records are written to the database \u2014 shorter intervals provide more real-time data but increase database load. The CDR retention policy determines how far back historical performance analysis can reach \u2014 operators who need 12-month trend analysis must ensure their CDR retention covers at least that period. <\/p>\n\n\n\n<p>The database performance also affects analysis speed \u2014 queries on very large CDR datasets (millions of records) may take several minutes to complete.
