I suspect your problem is with the softphone implementation...
definitely, the SIP spec iianm says that UACs should play a ringing
tone when the 180 is received.
Occasionally calls which go from 100 -> 180 without going via the
183 result in the Cisco ringing and combined rining genrated by
the telephone exchange which is weird but ok.
the supplementary question then is, since i can't change the
softphone would i break anything if i forced the sending of the 183
packet anyways from within chan_sip ?
Don't do it within chan_sip, do it within the dialplan by using
playback with the no answer option before you dial out...
You can check the user agent with a dialplan function.
