Hi,
Some weeks ago I managed to integrate osmobts with my asterisk server.
In the beginning, I did
not get any call progress, ( as opposed to running WITHOUT asterisk ). I
realized that defining
the msc to sipconnector socket effectively disabled all the logic
related to this.
To remedy the situation, I set an asterisk "progress statement" whenever
the extensions.conf
indicated a number belonging to my GSM network. This works OK, but now,
I don't get call progress
on calls toward PSTN. These extensions do not have "progress"
statements, since all SIP phones
interpret the call progress sip messages such as RINGING.
I am interested in your comments whether msc + sipconnector should
emulate mobiles as "sip phones",
it does seem to just silently drop call progress messages, and is this
the way it should work?
The functionality IS there, since when osmobts was bridging the calls,
call progress WAS there.
Well, I kludged up a solution for the GSM-only situation, and this seems
suboptimal.
I guess some clever asterisk hacking would solve that, possibly having a
redundant progress statement
on ALL extensions would do it, but would I not lose "actual" call
progress signals from the PSTN,
since asterisk would emulate them? Another way would be a small "local"
asterisk.....before the *real* one.
Boldly moving on to MultiBTS and handover....
