PVDM2-16 DSP on 2811 for transcoding ??

Hi,

I have a 2811 with a PVDM2-16 DSP.

It has no T1/E1/BRI/FXO or FXS cards.

I would like to use the 2811 as a DSP farm to transcode g711 to g729 streams from a Call Manager 5.

However I am not sure if this is possible, since when I get to voice-card config, and try and enter maximum transcode sessions, the only option is <0-0>

I am new to transcoding, and IOS gateways, so any pointers in the right direction would be helpfull.

Thanks

Hi

You might forget to put "dsp services dspfarm " under voice-card.

Please see the url for reference to configure transcoder or conference bridge:

I finally managed to get it work.

I had to put version 4.1 in the config, and use a profile.

My config is as below, for anyone interested.

sccp local FastEthernet0/0

sccp ccm xx.xx.xx.xx identifier 1 version 4.1

sccp

!

sccp ccm group 998

associate ccm 1 priority 1

associate profile 6 register MTPxxxxxxxxxxxx keepalive retries 5

!

dspfarm profile 6 transcode

codec g711ulaw

codec g711alaw

codec g729ar8

codec g729abr8

codec gsmfr

codec g729r8

codec g729br8
