Vladimir,

seen trace, it's like to firewall issue on avaya side (but possible on
asterisk side). Asterisk receive ack for all sended tcp packets except
connect packet for which ack isn't received. Asterisk try resend connect
message increasing resending interval step by step up to 2 mins between
tries. On 16th attempt reset packet arrive from avaya.
It's very similar there is l7 (application layer) firewall which can't
interpret signalling packets properly. Also i see you disable fast start
but don't capture h.245 sessions (it's additional tcp connect between avaya
and asterisk).
What firewall software you use on asterisk and avaya? Btw, i seen similar
troubles on old version h323 conntrack module from netfilter linux firewall
module.
By the way, you can try do tests with h245tunneling enabled on asterisk
and avaya, with latest patch it must work also. But i think what we can
accept this issue as resolved when we will receive god results for all
configurations of h.323 options.
