Yes. Why on earth do you send the call to Europe and back? Can you leave it in Boston? Question. Have you considered flashing the 7941s with the SIP firmware? As it stands right now, your voip gateways have to transcode the audio to Skinny to/from SIP. Question. Why not take some steps out of the equation, and terminate the SIP straight into asterisk? Question. What good is the Cisco gear doing in your diagram? Question. Assuming you ever get through, what does the audio sound like? Are your dropping packets and having the voice sound like garbage? Another suggestion: you can debug on the Cisco side too. The Cisco gear has a lot of choices to tweak DTMF, including sending it inband as audio tones. If you haven't already, get the thick Cisco manual that shows all the choices for DTMF that correspond to your gear. _______________________________________________ -- Bandwidth and Colocation Provided by http://www.api-digital.com -- asterisk-users mailing list To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users
