Hello,
Hope this is the right forum, if not please advise.
I own a ZyXel P-660R-ELNK DSL modem connected to a Netgear WGR615V unlocked router. After some fiddling, I managed to make the whole thing work with Callcentric a few months ago, and have been quite happy since. The original settings that I believe are salient were:
ZyXel ===== RIP direction: both RIP version: RIP-2B NAT mode: SUA only SIP ALG: enabled UPnP: disabled Security, filtering etc.: no special measures taken
Netgear ======= SIP proxy: callcentric.com SIP control port: 5060 SIP local port: 5060 SIP message TOS Value: 68 hex Starting RTP Port: 16384 RTP Data TOS Value: b8 hex Use Outbound SIP proxy: yes Outbound SIP proxy address: callcentric.com Outbound SIP proxy port: 5060 VAD: no STUN: no Register expire time: 30 sec Registration head start time: 0 sec DNS server: yes Primary DNS: 208.67.222.222 Secondary DNS: 208.67.220.220
It all works fine. Now, yesterday I found out that callwithus.com has better rates for my calling patterns, so I signed up. My new settings were:
ZyXel ===== unchanged
Netgear ======= As per
I hypothesized that the use of STUN somehow does not go well with the modem. Could that be the case? To confirm that, I also signed up with voicestick.com. They don't use STUN. They also are very shy about publishing their SIP client configuration. I fished one from this forum, which looks like this:
ZyXel ===== unchanged
Netgear ======= SIP proxy: 206.165.50.116 SIP control port: 5060 SIP local port: 5060 SIP message TOS Value: 68 hex Starting RTP Port: 16384 RTP Data TOS Value: b8 hex Use Outbound SIP proxy: yes Outbound SIP proxy address: 206.165.50.116 Outbound SIP proxy port: 5060 VAD: no STUN: no Register expire time: 30 sec Registration head start time: 0 sec DNS server: yes Primary DNS: 208.67.222.222 Secondary DNS: 208.67.220.220
However, that didn't work either! So now I'm back to my Callcentric setup which again works, and I can't understand how neither of the others work. Any insight would be appreciated. Thanks!
