Clarus Study Points out SIP Trunk Migration Hazards

And there isn’t even much debate about why it’s happening -- according to a good recent case study from Clarus titled "Clarus Services: SIP Trunk Business Readiness Verification," the primary driver of SIP adoption by enterprises is "the possibility to save costs versus alternative technologies just as Primary Rate Interface subscriptions and related PSTN gateways and elements."

Clarus Systems has considerable expertise in the area, having developed a SIP trunk business readiness verification service to detect and mitigate these risks, resolving issues while the migration process, earlier these issues can impact end users.

The company

The company, one of Clarus’s customers, is a global retail and investment bank, with "hundreds of bank branches throughout the US and offices across the globe." So we’re talking a sizeable operation, quite the challenge. The bank was migrating to SIP trunks and wanted Clarus to perform a SIP trunk business readiness verification.

Clarus performed a detailed series of verification tests. In the long run, they were able to advise the bank on the capacities for each individual network components, network element load balancing for each traffic mix, network element failover and redundancy configurations and the service routing for both primary and secondary route paths

The testing

Clarus as well identified several issues while the testing, including call disconnects resulting from packet loss or drops, blocked calls due to incorrect routing or capacity for call which route between multiple carrier switches / inter-switch trunk capacity, and misrouted calls, ones that are not routed as required once call capacity is exceeded.

Bottom line, without Clarus’ involvement, "the migration to SIP would have resulted in blocked calls, dropped calls and misrouted calls, with high impact to end users including the bank’s clients trying to reach them on inbound DID lines," according to Clarus officials.

Earlier this month TMC’s Juliana Kenny wrote that Clarus has been ramping up its global efforts in VoIP (Voice over Internet Protocol) management, involving expansive deployments and VoIP (Voice over Internet Protocol) infrastructure migrations and upgrades. Offering a remote service using U.S.-based resources to test global VoIP (Voice over Internet Protocol) phone deployments, Clarus is broadening its horizons in the Asian Pacific, Latin American, and EMEA regions.
