Advanced LCR (Least Cost Router) With SIP Proxy Server

Transcription

1 With SIP Proxy Server It s all about Reducing Cost!!!

2 WHY ADVANCED LCR (Least Cost Routing) Advanced LCR is a product by Advanced Communications; the same parent company of AdvancedVoIP.com, a widely used billing system by VoIP providers. The product comes from years of insight into the telecommunications and specially VoIP market place and real needs of VoIP operators to do least cost routing in a real world environment. NEXT STEPS Get Support AVPL (AdvancedVoIP.com) offers 24*7 technical support to its clientele.

3 Advanced LCR Advanced LCR provides next generation routing optimization solution that ensures service providers to automate and manage their routing processes by providing real time business intelligence on costs, profit margins, network issues etc. Figure 01: Standalone LCR Model Advanced LCR s routing method is comprehensive enough to ensure following factors: LCR data is loaded and stored in RAM i.e. RAM resident that ensures quick access of information. Financial matters in vendor agreements, complicated rate sheets, volume commitments and discounts. Network capabilities and constraints like near real-time measurements of network traffic volume, QoS and capacity. User defined business rules that improves quality and other standards for every switch, route class and includes override management.

4 Advanced LCR provides a user friendly interface that ensures definition of routing parameters. It enables routing collaboration and provisioning in the delivery of routing scheme. Figure 02: Working of LCR Model It allows carriers to modify rates/routes any time, for any terminator, without restarting the application. The solution supports the conventional voice switches and IP softswitches as well. Hence, it allows service providers to change routing schemes and rates in no minutes. Moreover, Advanced LCR is absolutely functional with SIP Proxy Server as the following figure shows:

5 Figure 03: LCR with SIP Proxy Server Advanced LCR not only searches for the best optimum route for call delivery in terms of cost but it also maintains the overall call quality. It precisely monitors the ASR (Answer/Seizure Ratio) of all the available routes and eliminates the route having minimum ratio from the final list of multiple routes. Both the scenarios working of LCR in terms of Cost and Quality are best illustrated in the figures shown below:

Some terminators offer the same rate for the entire day while some offer peak/off-peak rates separately. Thus, Advanced LCR proficiently handles different time rates for the same day.

9 Disadvantages of not using LCR Inability to handle a large number of terminators Tedious updating of static routing tables. Frequent errors and out of synchronization of static tables Difficult to reroute failed calls in real time while the call is being setup Difficult to change routes when a route fails Difficult to change routes when credit expires with any terminator Difficult to stop traffic over flow to limited capacity routes. Therefore without a LCR, telcos usually do one of two things. Keep a single account with an A Z terminator and send all traffic to him. Keep account with few terminators and manually manage the traffic routing. It is a known fact that without LCR, there is almost a 5% to 30% extra cost in calls delivery depending on technology the telecom uses. With telecom margins shrinking worldwide, this saving of 5% to 30% can translate into a 50% to 100% increase in the profit margin.
