Sad, but i don't know about config options for sua But in your log we have next: >> Account <sip:192.168.9.111:5060;transport=TCP> i think it's wrong because all others you use are on UDP transport, not TCP you need to remove "transport=tcp" from account info (you can also change it to "transport=udp" which is default) hope it will help :) -------------- next part -------------- An HTML attachment was scrubbed...
