CME and CUE DTMF not working

Hi all,

 

I have a CME on which SIP call arrives which I forward to CUE where I have IVR configured. This IVR plays some messages and offers some choices, however none of the digits I press on my phone comes to CUE.

 

Call flow: PSTN - CME - CUE

 

CME receives DTMF as inband and I can clearly see the digit signals when I take tcp dump on CME. I have transcoder configured and on DP to CUE I have dtmf relay sip notify. Also on DP to CUE I have g711ulaw while on inbound DP on which call arrives I have g711alaw. So since call connects I figure my transcoder is working, however DTMF is clearly not being transcoded. So why is my transcoder not transcoding DTMG but it's transcoding from g711alaw to g711ulaw?

 

radio-cme#sh dspfarm profile 1

Profile Service Mode : Non Secure
Profile Admin State : UP

Codec : g711alaw, Maximum Packetization Period : 30
Codec : g729ar8, Maximum Packetization Period : 60
Codec : g729abr8, Maximum Packetization Period : 60

 

I've attached sh run and debug ccsip for one test call. I changed calling number to 1001, and I deleted some info from sh run which I dont wanna disclose.

 

Appriciate any help in regards to this issue.

Hi,

 

thanks. This was first marked as spam and unavailable so I had to create another thread. Not sure what happen here.

We can use the duplicate and this can be closed.

 

BR,

Matija
