It's either 0.0.0.0 or 3264, but if their stack wont re-negotiate codec, you best set the HOLD for 0.0.0.0 or use g711 if you want it to work with sipx at all. > > under 'network parameters', there are the options nat_enable and > nat_received_processing (both, by default checked). wiki seems to > indicate I should disable these? but once done, phone will no longer > register. > > 2010-05-05 10:36:06.512170 76.108.146.15 -> 10.70.10.1 SIP Request: > REGISTER sip:204.89.241.150 > 2010-05-05 10:36:06.513102 10.70.10.1 -> 76.108.146.15 SIP Status: 401 > Unauthorized (0 bindings) > 2010-05-05 10:36:10.263878 76.108.146.15 -> 10.70.10.1 SIP Request: > REGISTER sip:204.89.241.150 > 2010-05-05 10:36:10.264832 10.70.10.1 -> 76.108.146.15 SIP Status: 401 > Unauthorized (0 bindings) > > Q should they be disabled? or not? > I may be wrong, it can happen. I think if the phone is behind nat it should be disabled. The REGISTER in sipxconfig should show sip:<user>@<public_facing_ip_where_phone_is> and later in the string "private-contact=192.168.10.11" (or whatever the phone has bound to it) If it shows the correct sequence I described above when it does register, you've found your own answer. > > Q also, "WAN IP address of the NAT or firewall server." is blank. should > it be the WAN address of the remote firewall 76.108.146.15? and should > nat_enable and nat_received_processing be checked? > > You static ip should say "static" and display the public facing ip on the firewall.
