I have a pri connection to the phone company. Sending DTMF out over the pri I hear on my phone when I call it. However, a second box uses a SIP connection to talk to the first box. When the second box is trying to do the function sendDTMF(1) over the SIP connection and then out the PRI I do not hear the DTMF tone at all. Everything else works over this connection just not the senddtmf function. In the sip.conf definition on both machines I have dtmf=rfc2833. What do I not have correct so that senddtmf() will work from the second box over the sip connection? THanks, Jerry
