vismAltCodecString2
Module: CISCO-VISM-CODEC-MIB
OID (symbolic): CISCO-VISM-CODEC-MIB::vismAltCodecString2
OID (numeric): 1.3.6.1.4.1.351.110.5.5.18.1.1.8
Node type: OBJECT-TYPE
Type: SnmpAdminString
Access: read-write
Description: This is an alternate codec string to that specified in vismCodecString and vismAltCodecString1. This object will also serve as a mapping string along with the vismCodecString and vismAltCodecString1 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 needs to be configured, this object will need to be configured second after vismAltCodecString1.
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 vismAltCodecString2?
This read-write SnmpAdminString object (0-64 chars) is a second alternate codec mapping string, used alongside vismCodecString and vismAltCodecString1 to match SDP descriptor strings in CRCX or MDCX messages, and requires the prior alternate to already be configured. This extends the number of distinct SDP naming variants the gateway can recognize as referring to the same codec, useful in environments interoperating with multiple call agent vendors simultaneously. An engineer supporting two different call agents that each label the same codec differently would populate this second alternate string with the second agent's naming convention.
