Hello Andrew,

thank you very much. I will check it out. I read RFC 4028 "Session Timers in the Session Initiation Protocol" and yes, this could be a solution. I would just have to be sure that at least one of the UAC supports the use of those timmers.

You should check the SST module: http://www.opensips.org/html/sst.html
