issue with auto attendant for incoming calls from PSTN

HusseinLTD

Level 1

Hi all, 

 

I'n new in the collaboration area, so please bare with me.

 

I have CME 11.5 installed on 4331 router, I have configured the auto attendant and it's working perfectly when testing from inside the network, but when I call from outside (PSTN) I hear the welcome message but I can't enter any extension, like when it says press 1 for sales or 0 for help, it doesn't matter what I choose, I keep pressing 1 and 0 but it's not redirecting me, it just keep reading the message and repeating it.

 

remember, this issue is only when call is coming from outside, when I test it from another ip phone it works normally.

 

I'm not sure if it's related to transcoding (that I have no experience about it)

 

show run file is attached

 

thank you

Since the autoattendant works correctly internally the issue is around DTMF negotiation from the SIP Trunk side.

 

Please attach a debug of the external call with the following debugs :

debug voip rtp session named-event

debug ccsip messages
