[Freeswitch-users] Generate 180/183 with SDP upon receipt of a 180 without SDP

[Mick Stevens]

Hi Andrew,

Many thanks for the prompt response.

Unfortunately it's this bit I don't want:

"Note that this may cause undesirable effects, like ringing for 3 seconds that turns into a busy signal."

Does this not do the trick? http://wiki.freeswitch.org/wiki/Custom_Ring_Back_Tones

Plays ringing tones (implying early media) if the remote channel is confirmed ringing and does not have early media. Unless I'm reading that wrong.

 happening. FreeSWITCH generally does all this for you, so I suspect there's a gremlin in the works. Can you pastebin a console debug log w/ SIP trace? That may give the gang here just enough information to figure out what's going on.

Where the ISUP carrier sends back an ACM with a backward call indicator of "subscriber free" the carrier sends a 180 without SDP to me/FreeSWITCH assuming that any ringback tones will be generated by the SIP user agent (RFC 3398 blah, blah, blah).
