Hi, I am having a problem when I add multiple phones behind a Symmetric Firewall. Heres my situation.
11am - Phone A registers with * 11:01am - test call to Phone A. Call works fine. 11:02am - Phone B registers with * 11:03am - test call to Phone A fails, test call to phone B works fine. 11:04am - test call from Phone A to Phone B and vice versa works fine. 11:05am - Phone A re-registers with *. Test call to Phone A works fine now. This happens on almost all occasions. When I see one phone register behind a firewall, i then see the "Retransmitting #5 (NAT):" messages, until I received the "Jul 13 15:11:09 WARNING[1133718080]: chan_sip.c:673 retrans_pkt: Maximum retries exceeded on call [EMAIL PROTECTED] for seqno 102 (Non-critical Request)" I have nat=yes in my sip.conf file. I have tried using the qualify command, but I have never been able to get it to work behind a symmetric firewall to both a unknown sip phone and xlite. The moment I turn on qualify, I see the Options request sent out, and on the client see the options request, but I never see a response on * from the clients. Here is what my sip.conf looks like... [general] port = 5060 bindaddr = 64.72.107.10 context = exten maxexpirey=3000 defaultexpirey=300 disallow=all allow=alaw allow=ulaw [123456] type=friend secret=k3v1n nat=yes canreinvite=no host=dynamic dtmfmode=rfc2833 context=cytelmain [789012] type=friend secret=cytel nat=yes canreinvite=no host=dynamic dtmfmode=rfc2833 context=cytelmain What else is there for me to try to resolve my NAT problem with multiple users behind a symmetric firewall?
