Hi, I came across an issue with Alcatel gateway. It was discussed in thread "RX msg 423 Interval Too Brief": http://lists.pjsip.org/pipermail/pjsip_lists.pjsip.org/2008-January/001198.html Shortly: Client (PJSUA) sends REGISTER request with Expires header, but the server answers 423 Registration Too Brief with Min-Expires header. As a consequence client should send new REGISTER request with new value of Expires, but PJSUA neither does so itself nor exposes the Min-Expires value to the user. I am writing about version 1.0.x and do not know how it works in 1.x branch. Can you suggest a clean solution of the situation while going deep as little as possible? Utilizing pjsua_internal.h is okay for me. Thanks - Vali
