Paul, Thanks for quick response. I am going to take a look at uac module much closely. Regards, Mac. _______________________________________________ Serusers mailing list serusers(a)lists.iptel.org http://lists.iptel.org/mailman/listinfo/serusers .

OK, i have new compilation of SER (CVS HEAD) with uac module. Unfortunately there is another problem i cannot overcome. What i need is to add "49" at the beggining of the calling number in INVITE message. For example change xxxxx into 49xxxxx. That's all. I am only concerned about the traffic originated on PSTN side through Cisco AS5300. uac_replace_from("sip:49xxxxxx@10.10.10.22") or simply replace("From: <sip:", "From: <sip:49") are doing this job properly, but - i get no ringback tone on PSTN side, deadair, and the call is droped after few secs. - there is a ringtone on IP side (softphone) Do you have any ideas what could be the problem.? I quess that the reason might be following: - cisco is originating the call with calling_nr xxxxxx, thereby sending INVITE with xxxxxx - all other signalling messages comming from IP side have got 49xxxxxx calling number - so the caller isn't the same. I would like to Cisco stay away from this matter, and use SER in this case. Any help?
