firewalls and OBI, Callcentric, GV and dd-wrt w/SPI

On the contrary, I believe that OBiHAI support team has replied to RonR's
"suspected bug report" promptly via email and has suggested that the problem is likely to
be caused by STUN being enabled on his unit.
However we did not get any further confirmation from RonR
whether turning off STUN fixes the issue. We do not believe there is a bug in
RonR's case which we are not able to reproduce.
RonR might have a very unique setup that may not apply to other users.
Disabling the STUN server had no effect on the problem.
In my case, things appear to get tangled up in the OBi when a BYE is received from a SIP provider for a call that is connected to a phone via SIP on a PAP2. The PAP2 session terminates properly, but the SIP provider apparently never gets an OK response from the OBi and keeps resending BYE's until it retries out. Both SIP sessions are going through SP2/ITSP B and it appears the OBi doesn't keep the two sessions separated and loses track of things.
I've attached a Syslog showing repeated BYE's from tollfree.future-nine.com with no response from the OBi.
I'm of the opinion that it's a firmware problem as it did not occur prior to upgrading to v1.3 and my setup hasn't changed in the meantime.

I think I am back to where I started then assuming it is the router and not wanting to disable my firewall.
So how best to configure my router to keep Obi happy and keep my network computers properly protected?
Note that Callcentric doesn't recommend that you disable your firewall. They only recommend that you disable SPI on your firewall... big difference! ;) Some people argue that SPI doesn't belong in the firewall in the first place; the bottom line - if you disable SPI, all your firewall protection will remain in place.
Actually I tried disabling SPI and tested before and after on “shieldsup”. With SPI I was fully protected, no holes in the firewall, without several vulnerabilities were listed. Needless to say I have chosen to leave it on.
My workaround has been to rout outgoing calls via GV and incoming via callcentric. The call times on the callcentric web site continue to show a cpl of minutes longer than the OBI call logs so I assume this is still an unresolved issue.
Just to reiterate, callcentric claims they do not receive a “BYE” from the OBI at the end of a call and this started with firmware ver 1.3
nmssystems1:
I would say try a different router. easy check to see if it is some thing in your dd-wrt or if it is the obi..or calcentric..
also why are you using the min version of that dd-wrt why not the standard generic image..
The other thing to try if you do not have another rotuer handy is to do the 30-30-30 reset of the dd-wrt router.
thanks
good luck.
