vismAltCodecString3

Module: CISCO-VISM-CODEC-MIB

OID (symbolic): CISCO-VISM-CODEC-MIB::vismAltCodecString3

OID (numeric): 1.3.6.1.4.1.351.110.5.5.18.1.1.9

Node type: OBJECT-TYPE

Type: SnmpAdminString

Access: read-write

Description: This is an alternate codec string to that specified in vismCodecString vismAltCodecString1 and vismAltCodecString2. This object will also serve as a mapping string along with the vismCodecString, vismAltCodecString1 and vismAltCodecString2 objects and the VISM will use the value in these objects to match the SDP descriptor string obtained for a codec in a CRCX or MDCX(ModifyConnection) message.

If alternate codec strings need to be configured, this object will need to be configured third after vismAltCodecString1 and vismAltCodecString2.

The local connection option or SDP(Session Description Protocol) descriptor string that VISM would get from the call agent for the codec to be used will be in the form of PCMU, PCMA, G726 at rate 32 kbps, G729a, CCD ..... where in PCMU stands for G711u PCMA stands for G711a and CCD stands for clear channel

This is an optional parameter which, if not configured, has a default value as specified.

What is vismAltCodecString3?

This read-write SnmpAdminString object (0-64 chars) is a third alternate codec mapping string, used along with vismCodecString, vismAltCodecString1, and vismAltCodecString2 to match SDP descriptor strings in CRCX or MDCX messages. This provides a third layer of naming flexibility for environments where yet another call agent or SDP convention must be recognized as referring to the same codec. An engineer onboarding a third distinct signaling source with its own codec naming scheme would populate this object with that source's specific SDP string.
