Hi
it was solved when alcatel allowed all the codecs.
if alcatel allows only G.729 then the call is not established
other observation is we have mivoice 400 ver 4.1 and Mivoice 400 ver 6.2 .
when alcatel allows only G.729 then call is established from Mivoice 400 ver 6.2 , but no calls are possible from Mivoice 400 ver 4.1.
Regards
