transcode incoming calls and IVR

nmdc.kzstan

Hi,

Transcoding is working fine for incoming SIP calls. ITSP supports only g711alaw so it is hardcoded on incoming dial-peer.

How do I transcode incoming g711alaw calls to g711ulaw (its-CISCO.2.0.3.0.tcl) IVR? For transcoder to be invoked incoming and outgoing

dial-peers are needed, but in IVR calls there is only incoming dial-peer.

Now if I call external number from PSTN IVR I don't hear welcome message and after some time forwarded to operator number.

TIA

Hi

1- You have to enable transcoder .

2- under the dial-peer which go to IVR , use codec g711ulaw.

3-match transcodig under your telephony-service.

Hi,

The problem is there is no dial peer to IVR, only incoming dial-peer 210. I have working transcode config and if call is

forwarded to CUCM via SIP trunk call is transcoded.

 service meetme  -----> IVR
