1) *Please* remove all ports forwarding, you don't need *any* of them
for your setup;
2) Check that no SIP ALG (Application Layer Gateway) is enabled on your
router. If yes disable it. Google for your make and model if there's no
obvious way to check / disable it. The damn thing is more harm than good
in 99.99% of the cases.
3) If the router has a VoIP section, do your utmost to disable it
completely. If you can't, move all ports for all settings well away from
4) *Always* set an outbound proxy in all accounts. For Sipgate, the
setup I use is:
General Provider Data
Proxy server address: sipgate.co.uk
Proxy server port: 5060
Registrar server: sipgate.co.uk
Registrar server port: 5060
Registration refresh time: 600 sec
STUN enabled: [X] Yes [ ] No
STUN server: stun.sipgate.co.uk
STUN port: 3478
STUN refresh time: 999 sec
NAT refresh time: 999 sec
Outbound proxy mode: [ ] Always [X] Auto [ ] Never
Outbound proxy: sipgate.co.uk
Outbound proxy port: 5060
As per Draytel, never used them but I gather their outbound proxy is
"nat.draytel.org" on port 5065.
See here: http://www.draytel.org/resources/ima...ens_S450IP.gif
As DTMF method settings, have enabled *only* the RFC2833.
It'll be £ 10 + VAT for the consultancy, who do I send the invoice to?

Thanks for the quick & comprehensive reply Bodincus,
From the top;
1) I have now disabled all open port forwarding to the S685IP
2) SIP ALG was already disabled. I had checked previously via Telnet using
the sys sip_alg ? command line and it returned a 0
3) I have now removed entries for Sipgate & DrayTel from the 2820Vn VoIP
section. Ironically it was the DrayTel account that was showing as
registered in the router while the Sipgate was not!
4) Why would I *Always* set an outbound proxy if using STUN on Sipgate for
example? I would prefer to use STUN for everything but DrayTel don't support
it. I am new to VoIP so please be gentle with me if I have misunderstood!
My Provider data for Sipgate is similar to yours apart from my having lower
refresh times than 999 and having 'Never' checked for Outbound proxy mode as
it uses STUN
I have followed your recommendation for using the DrayTel Outbound proxy as
per that difficult-to-read picture from DrayTel themselves and changed my
Send Settings from Auto to RFC2833.
I still can't hear any audio but now in addition I can't even get the
DrayTel account to connect...it sits there a while and then gives Error 701.
At least before it connected and the timer incremented despite my not
If I disable the Outbound Proxy mode then I can again connect...but back to
square one as still no audio can be heard.
Consultancy fee? No problem...give me a call...via DrayTek VoIP and you can
tell me where to send the cheque ;^)
Valiant attempt...I appreciate your help.
Thanks & kind regards,
