Dear Matt, nice to meet you! Thank you for your prompt response. The Avaya's phone 9608 and 9641 don't work in UDP, when status is just trying register, but not happen. So, with TCP they register correctly on Asterisk, version 1.8.32.3. The calls works fine, but other features not, like hints, capture, moh, contact list, transfer, conference, etc. So I'm looking for more details or solution to this case, but I can't. Below my sip.conf and sip debbug of 9608 peer, these informations help? One more time, thank you so much! The logs is here: http://pastebin.com/tnxVgeJT With Best Regards Diogo.
