Hi there, I have very strange behaviors for my SIP endpoints with FS SVN trunk 15905. I tested with both Polycom IP650 and Bria 2.5.4, compared against port audio and googletalk endpoints in the same network. all SIP end points (Polycom and Bria) behind NAT but in the same subnet 192.168.0, I tried to change the settings below: <param name="local-network-acl" value="localnet.auto"/> <param name="apply-nat-acl" value="nat.auto"/> in /conf/sip_profiles/internal.xml using different combinations of either enabling or disabling them. the results are all the same, the audios on sip endpoints always got cut about 31 seconds, no issues at all with either port audio or gtalk, Could anyone point me to the right direction for the sofia_sip profile setup? Your helps are greatly appreciated Thanks, Chris
