Getting SIP to work on Obi 202

<< < (4/4)

Thanks for the correction about STUN.

I had actually attempted to enable registration. But it seems that Voxbeam doesn't support SIP registration.
So I unchecked that option since it was failing to register.

Unless you are saying that it's ok to enable registration
even if the voip provider doesn't support it, with the whole intent for obi to send the external/public
IP address as part of the SIP message.

I just attempted what hwittenb hinted:

I enabled registration with the VOIP provider even though my provider doesn't
support registration (when I go to the Status page of the Obi, it shows that "register failed" for SP4).
And on top of that, I removed from the X_PublicIPAddress my external IP address.

Apparently things continue working which confirms that the Obi will sent the public IP address
when registration is enabled, regardless if registration succeeds or not. And apparently
the Obi was sending the internal IP address when registration was disabled.

This was quite enlightening ...

hwittenb:
It's good to know that it works both for register succeed and register fail.  I didn't previously test register fail.

The OBi will continue to try to register.  If you had any other voip provider that would register you could configure that configuration under SP4 to register successfully.  You could get a free CallCentric or Sip-to-Sis account if you wished.  It wouldn't affect your incoming calls.

You previous stated that you forwarded the sip signalling port for SP4 in your router to the OBi202.  It should be noted for anyone else that this forwarding is required in this type of use.
