IPIPGW without CCM

Unanswered Question

I've been trying to test IPIPGW to transcode SIP calls from g711 to g729. All the examples I found seem to involve SCCP/CCM, is there any info about whether IPIPGW can be used with non-CCM setup?

I'm interested to use the IPIPGW function as generic hardware codec trancoder for different end-points capabilities, just plain codec transcoding sessions on SIP without any conferencing features.

Is there any official info on whether CCM is a 'must' on transcoding feature for IPIPGW?

YEs you can,

Implement CallManager Express in the same IPIP GW and configure TRASNCODER in there.

That should do it.

I followed the CME configuration. But there are missing command like 'dspfarm profile...', 'sccp group... associate ccm' on IOS c3725-adventerprisek9_ivs-mz.124-15.T1.bin.

Is it not the right version for ipipgw and transcoding with local CME?

If I try #show sdspfarm units, the info said i'm not registered for the MTP.

I think it's not necesary to configure MTP since you are not using a CCM server. Configure Transcoding only ...

sccp local FastEthernet0/x

sccp ccm identifier 1



sccp ccm group 1

associate ccm 1 priority 1

associate profile 1 register CONFERENCE

keepalive retries 5


dspfarm profile 1 transcode

codec g711ulaw

codec g711alaw

codec g729ar8

codec g729abr8

codec gsmfr

maximum sessions 4

associate application SCCP

Hope it can help you
