I’m currently leveraging a Sonus Session Border Controller with AT&T to provide SIP trunking to a legacy Avaya Communication Manager for a large customer contact center. The Sonus SBC supports a fix number of concurrent calls because of the T1 CAS signaling to the legacy Avaya platform. So I’d like to know when and if we max out that capacity and measure the daily call volume. We can get the data from the legacy Avaya Communication Manager and from Avaya Contact Center but it’s much easier to collect that data from the SBC via SNMP.
I’ve done work in the past with Audiocodes Mediant 1000 but this time around I decided to let AT&T provide and manage the SBC. Ask me in a year how that worked out for me?
Here’s a copy of the SONUS SNMP MIBs.
I choose to graph the following SNMP OIDs;
- uxNumCallAttempts (.1.3.6.1.4.1.177.15.1.5.19.1.0)
- uxNumCallSucceeded (.1.3.6.1.4.1.177.15.1.5.19.2.0)
- uxNumCallFailed (.1.3.6.1.4.1.177.15.1.5.19.3.0)
- uxNumCallCurrentlyUp (.1.3.6.1.4.1.177.15.1.5.19.4.0)
That should give me a good idea of the concurrent channel utilization and hourly/daily call volume.
Here are some interesting SNMP OIDs for the Sonus Session Border Controller.
