[Spce-user] dtmf issue to Jon

[Akhil Chandra]

Hey Jon,

Not sure what the issue was. It is working now. I think the issue may be the IVR that I was directing to was not set up properly.

I can also login to the voicemail. 

But when I get to pressing 3 for advance options, it just gives me an option stating that "press * to return to the main menu". How do I set my greeting and name in the voicemail.

Akhil

what about if you call sip:provider's voicemail server? It should be
rfc2833 unless you changed it in config.yml.

If it's another asterisk server you cannot be sure of the method unless youcheck the asterisk config or debug or capture because asterisk supports rfc8233, inband and info methods. 

Most probably you're sending SIP INFO method, not allowed by sip:provider, to send dtmf. Try setting dtmf=rfc8233 in sip.conf or check if you can see SIP INFO packages using ngrep-sip while pressing those dtmf.

Inband and rfc8233 transports the dtmf in media. SIp:Provider is at the moment transparent to media, so I can only think in the INFO method at the moment to explain the behaviour.

Not at the moment. You need tcpdump + wireashark. we have a sipcapture module but AFAIR it wasn't released in 2.5CE.
