vismAltCodecString1

Module: CISCO-VISM-CODEC-MIB

OID (symbolic): CISCO-VISM-CODEC-MIB::vismAltCodecString1

OID (numeric): 1.3.6.1.4.1.351.110.5.5.18.1.1.7

Node type: OBJECT-TYPE

Type: SnmpAdminString

Access: read-write

Description: This is an alternate codec string to that specified in vismCodecString. This object will also serve as a mapping string along with the vismCodecString object 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 first.

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 vismAltCodecString1?

This read-write SnmpAdminString object (0-64 chars) is an alternate codec mapping string to vismCodecString, used together with it to match SDP descriptor strings received in CRCX or MDCX messages, and must be configured before any further alternate strings. This gives an admin a way to recognize multiple different SDP naming conventions for the same underlying codec, useful when interoperating with call agents that don't all use identical codec string naming. An engineer connecting a VISM gateway to a call agent using a nonstandard SDP codec label would populate this alternate string with that exact label so the mapping still resolves correctly.
