I am having trouble with a Panasonic D500 that is connected to an Asterisk server via an E1 and then the Asterisk server dials out via a SIP provider. The problem is that DTMF is not being recognized when they try to call an external IVR like a bank service. If I connect a SIP phone to the Asterisk server and dial using the SIP line I can use the external IVR, but when al call is placed from a phone connected to the Panasonic D500 the IVR will not respond. I am using Asterisk 1.2.10 on CentOS 4.4 and the Panasonic is connected using Unicall on a TE110P. I know DTMF is fine from the Panasonic to the Asterisk because I can dial the Voicemail extension and navigate the menu, it is just when we try to get an external IVR that we have a problem. -- Carlos Chavez Prats Director de Tecnolog?a Telecomunicaciones Abiertas de M?xico S.A. de C.V.
