My C2951 is connected via sip trunk to provider.

A provider's station supported only sip-info dtmf method.

Re: Sip-info DTMF not working

Try using a different dtmf-relay function you have sip-notify set and you are not using the notify verb in your signaling.

Allow: INVITE, ACK, BYE, CANCEL, OPTIONS, INFO, UPDATE, REGISTER

You will need to allow Notify to use the INFO dtmf method.

Or try dtmf-relay rtp-nte to start with.

you may also need to set voice rtp send-recv but try it without to start with if you need out of band digits use

dtmf-relay rtp-nte digit-drop to the dial-peers

Sip-info DTMF not working

Hello Tim. Thank you for your response.

"You will need to allow Notify to use the INFO dtmf method." - please verify, I did not understand.

In that document

http://www.cisco.com/en/US/docs/ios-xml/ios/voice/sip/configuration/12-4t/voi-sip-dtmf.html#GUID-0E228A53-4405-4730-8D54-B37979E69A8B

I don't find additional commands to enable INFO dtmf method.

In sip-ua I added " notify telephone-event max-duration 200" , but it not help.

"Or try dtmf-relay rtp-nte to start with." - I tried it, but the provider's station supported only sip-info dtmf method.

Re: Sip-info DTMF not working

CUCM and IOS gateways can receive SIP INFO (RFC 2976) messages for DTMF but cannot generate them (CSCse50733)

You will need to get a provider that supports other form of DTMF e.g rtp-nte.SIP-INFO is old and deprecatted

Sip-info DTMF not working

Pavel,

Since you are receiving SIP-INFO from the third party station, what is the dtmf method we are negotiating on the other SIP leg with your provider?

Take a look at sip signalling on both legs using "debug ccsip message" and see the DTMF method negotiated on both legs. This should you go further.

Regards,
Avinash
