<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;
font-family:Arial'>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?</span></font></p>
