Type: INTEGER
Access: read-write
Description: This attribute defines the codec Type used for the connection.
'g711u' represents PCMU with 64 kbps. 'g711a' represents PCMA with 64 kbps. 'g726r32000' represents G.726 at rate 32 kbps 'g726r16000' represents G.726 at rate 16 kbps 'g726r24000' represents G.726 at rate 24 kbps 'g726r40000' represents G.726 at rate 40 kbps 'g729a' represents G.729 Annex A algorithm. 'g729ab' represents G.729 Annex A and Annex B algorithm. 'clearChannel' represents CCD with 64 kbps. 'g723h' represents G.723.1-H at rate 6.3kbps. 'g723ah' represents G.723.1-H at rate 6.3kbps with Silence Supression ON. 'g723l' represents G.723.1-L at rate 5.3kbps. 'g723al' represents G.723.1-L at rate 5.3kbps with Silence Supression ON. 'lossless' represents Lossless
Note : 1. When codec type is 'clearChannel', vismAal2CidProfileType and vismAal2CidProfileNum are not applicable and will be ignored.
2. Value 10 is RESERVED.
What is vismAal2CidCodecType?
This read-write INTEGER object selects the voice codec used on a connection, from options such as g711u (PCMU 64kbps), g711a (PCMA 64kbps), several G.726 bit rates, and G.729 variants. The codec choice directly determines both call audio quality and the bandwidth consumed per channel, since higher-compression codecs like G.729 use far less bandwidth than uncompressed G.711. An engineer trying to fit more simultaneous calls onto a bandwidth-constrained trunk would set this object to a compressed codec like g729a rather than g711u.
