I am testing asterisk-1.2.1-15 on RedHat 9(i386) for SIP-to-SIP call and i found a strange problem. When an extension gets a ring and it picks up the call a "tick" sound comes at start. This happens on both sides. I tried Xten's softphones and also hardphones. A thing which was common in both(soft/hard phones) was the selected codec. When i used g711ulaw on both soft/hard phones the ("tick")sound was much audible.As i shifted to g711alaw the ("tick")sound got fade, and on g729 it was completly gone. Also strangly this same thing happened when i tested on some other servers other that asterisk. Is there anything related with codec selection. Any help is greatly appriciated.
