CallManager Express 7.1 with Unity Express forward problem IOS 15.0 2900 router

Hi there,

I'm trying to get calls forwarded to voice mail ISM0/0 and calls are dropped.

Normally this ip phones receive calls with g729a from H.323 signaling, i configured a forward no answer to voice mail. When the call is not answered it tries to forward to voice mail with SIP signaling, but the call fails (i believe that transcoding is not coming up with the interworking). I have interworking configured and transcoding - i will post the config.

If i put an incoming dial-peer (dial-peer 7 voip) with g711ulaw to that E.164 phone number (to get calls forwarded to voice mail but with the codec g711ulaw from the PSTN) calls enter voice mail with sucess. But if i take out that dial-peer that call fails, as i previously described.

P.S. - i configured two type of transcoding for testing and both do normal transcoding.. as you can see below

#sh sccp connections

sess_id    conn_id      stype mode     codec   sport rport ripaddr

7          8            xcode sendrecv g729    32636 2000  134.134.134.88
7          7            xcode sendrecv g711u   16386 2000  134.134.134.88

Total number of active session(s) 1, and connection(s) 2

Thanks everybody!

Hi,

From your config I can see:-

!

telephony-service

voicemail 1020

!

!

That means you should have a SIP dial peer pointing to the VMAIL

!
dial-peer voice 1020 voip
destination-pattern 1020
voice-class codec 1
session protocol sipv2
session target ipv4:YOUR VMAIL IP ADD

Actually, he has that covered using dial-peer voice 5 voip.

Dial-peer 6 though sure has me scratching my head.  Not sure what that one is for. 

Try this:

Get rid of this DSPFarm profile all together:

dspfarm profile 21 transcode

codec g711ulaw

codec g711alaw

codec g729ar8

codec g729abr8

codec g729r8

maximum sessions 3

associate application SCCP

shutdown

!

Modify this one as follows:

dspfarm profile 23 transcode universal

codec g711ulaw

codec g711alaw

codec g729r8   <=   all other codecs removed

maximum sessions 4

associate application SCCP

I will say that normally you don't need to do this.  I'm not sure why you are needing to.  You should be able to get this to work without having any transcode resources configured PROVIDED all the calls are coming in from the PSTN, and not coming in as G729 over the WAN.

Hi there,

The calls are coming from PSTN with g729 codec and failing. Only when i activate dial-peer 7 the calls are successful because all legs are g711ulaw and no transcoding is needed.

Have you done a debug on the dial-peers to determine which dial-peers are getting engaged during setup?  I'm wondering if you're hitting the default dial peer, which will NOT negotiate codec.

Hi there, the call is coming in through dial-peer 2,

   Calling Number=300504602,(Calling Name=)(TON=National, NPI=ISDN, Screening=User, Passed, Presentation=Allowed),

   Called Number=210042822(TON=National, NPI=ISDN),
