Does anyone know where I can get full documentation of how to implement the SR140 on a cisco network? I have looked all over the place and cannot find any documentation.

On your H323 gateway under inbound calls do you have enable inbound faststart?
And when you say outbound dialing do you mean outbound to your extension or outbound fax's are transmitting fine?

I have tried it with and without inbound faststart. I can dial 10 digit and internally to my number. I receive the fax tone when I answer it.

So it sounds like a gateway issue. Can you do a show mgcp and attach it.

Sure, Here is a snippet:

For some bonding calls through the H.323/H.320 gateway, the gateway requires a longer time to exchange the H.323 TCS message. If the time required is greater than the timer setting for several Cisco CallManager service parameters, Cisco Unified CallManager will drop the call.
If the default Cisco Unified CallManager gateway timer values appears to be too short, Cisco Unified CallManager drops the call before completion of the call connection. Cisco recommends increasing the following service parameter timers values to avoid call failure.
â¢H245TCSTimeout=25
clusterwide parameters (Device - H323)
â¢Media Exchange Interface CapabilityTimer=25 clusterwide parameters (service)
â¢Media Exchange Timer=25
clusterwide parameters (service)

I tried changing these parameters, but I get the same result

Just an update. We just found out that CCM 5.1 and Captaris isn't supported with the H323 gateway setup. CCM 6.X is supported and will work. I plan on upgrading a site mid next week and seeing if this is the cause.
02-05-2009 05:47 AM
ok, here is what I have found. I was using RightFax 9.3 FP2 SR6. I tried the BrookTrout test utility and it worked! I then realized that the .dll and .exe versions were slightly different, so I renamed the old ones in the DocTransport and system32 directories, copied over the newer ones from the FD54 directory and tested successfully. The key files were the bostsrv.exe, bostsrv.dll, bostdlld.dll and brkth323.dll.
Another thing that I found was that there are preferred settings that I couldn't find documented anywhere.
Within the BrookTrout Configuration, Click BT Call Parameters and the Advanced. Disable the V.34 options (3 of them). Change the "Number of Cycles Before Failure" to 3. Then go to the H.323 IP Parameters and expand the Advances section. Set h323_FastStart to 0, h323_H245Stage to 3 and h323_h245Tunneling to 0. Then go to the T.38 Tab. Make sure the Media Renegotiate Inbound to 4000 and Outbound to -1.
02-05-2009 06:00 AM
Thanks for that. I had the H.323 IP parameters all set correctly. But I had all the V.34 options enabled and the Number of Cycles Before Failure to 1.
I wonder if that is why we were getting so many transmission errors on incoming fax's.
02-05-2009 07:22 AM
that's possible. It will be interesting to see if you get a better success rate. It would be nice if Cisco had better documentation for using the SR140.
02-05-2009 07:24 AM
I completely agree with that.
Currently we have a 7% error rate with inbound faxes. I will give an update in a couple of weeks and see if it goes down.
Thanks again for info.

Hi all,
Someone said it is not supported to integrate Rightfax via H323 to CCM 5.1.
Is it really unsupported?
I'm trying to setup Rightfax 9.4 as an H323 gw in a CCM 5.1.2 but It seems through wireshark that Rightfax is not transmiting any RTP packets(although it recieves)
05-06-2009 05:35 AM
That is correct. I had a problem at a site setting this up and both Cisco and Captaris confirmed that it's not supported. Not exactly sure why not.
01-20-2009 04:44 AM
How could you able do that, Am not able to make FAx server directly talk to Cisco voice gateway.
I had added a h.323 client in CCM with the IP of fax server then it started working. else its not our problem its wth the SR 140
