I've got asterisk working great with cisco 7905 sip phones. I've just got one issue that I can't figure out. I have a 5300 connected to the PSTN via PRI. When I send a call from the 5300 to asterisk it will ring the 7905 phone for 4 seconds then drop. This is because the only message asterisk sends to the cisco is the 100 trying message. The 5300 receives that and sends a call proceeding message back up the pri. A 4 second timer is then started while it waits for a 180 ringing or 200 OK message. The 7905 sends a ringing message to asterisk but asterisk doesn't pass it back to the cisco. So unless the person at the phone answers in 4 seconds the cisco will disconnect the call. Any ideas?
