Hi I have a very strange issue.
Using a Cisco 2811 router with PRI connecting to customers PBX. SIP trunk towards Verizon. Incoming and outgoing calls are working just fine, using G.729 codec. DTMF RFC288 configured, and I can see in the SIP invites and 200ok messages that it is indeed using RFC2833. However, when customer makes an outgoing call, and the press any key, I can hear the tone, and I see the DTMF in the router with debug voip rtp session but after that, RTP is dead in the outbound direction.
