But what happens when a routing decision sends a call through a gateway where the clearing rate is higher than the caller rate, resulting in a loss? Without a safeguard, VOS3000 will happily route calls through unprofitable gateways, silently eroding your revenue. The <strong>VOS3000 lowest profit rate limit<\/strong> parameter solves this by locking a gateway when the profit falls below a configurable threshold \u2014 and uniquely, it supports negative values, enabling strategic loss-leader routing scenarios. \ud83d\udd27<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">\u2699\ufe0f According to the VOS3000 V2.1.9.07 Manual \u00a72.5.1.1 (page 34), the VOS3000 lowest profit rate limit is defined as: &#8220;Lock this gateway when profit below settings. When the difference, calculate by rate per second, between caller fee rate and clearing fee rate lower than the value, this gateway won&#8217;t be tried. Negative is supported.&#8221; This means the VOS3000 lowest profit rate limit calculates profit per second (caller rate per second minus clearing rate per second) and excludes the gateway when the calculated profit is below the threshold. The support for negative values is a critical feature that enables loss-leader strategies. \ud83d\udcca<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">\ud83c\udfaf This guide provides a complete, manual-verified reference for the VOS3000 lowest profit rate limit.

A negative VOS3000 lowest profit rate limit means that VOS3000 will allow the gateway to be used even when it generates a loss \u2014 up to the specified negative threshold.

This is useful when you want to offer competitive rates to new customers at a temporary loss, knowing that long-term customer retention will generate profit through volume and other routes. The VOS3000 lowest profit rate limit with negative support gives you the strategic flexibility to make intentional loss decisions with a defined maximum loss threshold.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"\ud83d\udcca-vos-3000-lowest-profit-rate-limit-and-sort-by-rate-interaction\">\ud83d\udcca VOS 3000 Lowest Profit Rate Limit and Sort by Rate Interaction<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">\ud83d\udd17 The VOS3000 lowest profit rate limit interacts with the &#8220;Sort by lowest rate per second&#8221; setting and the SS_GATEWAY_ASR_ROUTE_SORT_CONFIG parameter.

A call that lasts 15 seconds with per-minute billing may be rounded up to a full minute, making the profit appear acceptable on paper. However, the actual profit per second of that 15-second call may be below the threshold. The VOS3000 lowest profit rate limit uses per-second calculation to ensure accurate profit assessment regardless of call duration, preventing thin-margin short calls from slipping through.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"\u2753-what-does-a-negative-vos-3000-lowest-profit-rate-limit-mean\">\u2753 What does a negative VOS3000 lowest profit rate limit mean?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">\ud83d\udd04 A negative VOS3000 lowest profit rate limit means that VOS3000 will allow routing through the gateway even when the call generates a loss, as long as the loss per second does not exceed the absolute value of the negative limit. For example, a limit of -0.005 means calls can lose up to $0.005 per second before the gateway is locked. This enables loss-leader routing strategies where you intentionally accept small losses on certain routes to maintain customer relationships, penetrate new markets, or comply with regulatory requirements that mandate service availability even at a loss. The VOS3000 lowest profit rate limit negative support ensures these strategic losses are bounded.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"\u2753-does-the-lowest-profit-rate-limit-apply-when-the-caller-has-no-rate\">\u2753 Does the lowest profit rate limit apply when the caller has no rate?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">\ud83d\udccb When there is no caller fee rate for the destination (the caller&#8217;s rate table does not have a matching entry), the profit calculation cannot be performed. In this case, the VOS3000 lowest profit rate limit behavior depends on whether the &#8220;Check rate&#8221; feature is enabled. If Check rate is enabled, the gateway requires a clearing fee rate to exist, and without a caller rate, the profit appears as negative infinity, which would lock the gateway. If Check rate is disabled, the call may route without rate verification. The VOS3000 lowest profit rate limit works most reliably when both caller and clearing rate tables are complete and consistent.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"\u2753-how-does-the-lowest-profit-rate-limit-differ-from-max-minute-rates\">\u2753 How does the lowest profit rate limit differ from Max minute rates?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">\ud83d\udcca The VOS3000 lowest profit rate limit and Max minute rates serve different purposes. The VOS3000 lowest profit rate limit checks the <em>profit margin<\/em> (caller rate minus clearing rate) and locks the gateway when the margin is too thin. Max minute rates check the <em>absolute cost<\/em> of the clearing rate and lock the gateway when the per-minute rate exceeds the ceiling. A gateway can be locked by either condition independently. The VOS3000 lowest profit rate limit catches margin issues (even if rates are low, the margin may be too thin), while Max minute rates catch cost ceiling violations (even if the margin is acceptable, the absolute cost may be too high). Using both together provides layered protection for your revenue.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"\u2753-can-i-set-different-profit-limits-for-different-gateways\">\u2753 Can I set different profit limits for different gateways?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">\ud83d\udd27 Yes, the VOS3000 lowest profit rate limit is configured per-gateway. Each routing gateway can have its own VOS3000 lowest profit rate limit value. This means you can set a tight profit limit on premium gateways (e.g., 0.001\/sec) to ensure healthy margins, while setting a more relaxed or negative limit on competitive gateways that are used for market share. The per-gateway flexibility of the VOS3000 lowest profit rate limit allows you to implement differentiated profit strategies across your routing infrastructure. Need help configuring profit limits?
