Question

FOIP outbound fax not working Fax Over IP with Cisco router not sending our RM (request mode) on secoond leg of call with the result of a t30 timeout (quite). Inbound seems to work fine.

Asked by: bitorandthesnowdog

We have a Cisco 2821 with the latest IOS and we are working with an expert vendor (Cisco Gold partner).  Been troubleshooting and taking wireshark traces for two weeks, and neiter Cisco nor Cantata (brooktrout) the makers of the SR140 card seem to be able to give an answer.  What it has come down to is, cantata is saying that the Cisco router is not sending out a RM (request mode) back to the fax server (according to Cantata, the SR140 "virtual" fax board, is not supposed to generate the RM, but the router should and send it to the fax server.)  This results in a t30 timeout.  The latested show run is pasted in below from the router, so if any of you Cisco VOIP genusies that may have worked with the SR140, may be able to see what is missing in the router config.  The SR140 is configured correctley as far as the card manufacture say.

I have the *exact* same issue.

Cisco 2821 VOIP voice gatway with SR140.  I've been working with Cantata on the problem and they say it is a Cisco problem as well.  Someone has to be doing outbound faxing with either an SR140 or TR1034 board via a Cisco gateway...  My voice gatway config is very similar to your posted above.

 

by: brianj51Posted on 2008-02-28 at 14:37:36ID: 21008988

I got it to work:

Here are the key points:
Cisco Config:
voice service voip
   fax protocol t38 ls-redundancy 0 hs-redundancy 0 fallback none

My dial peer looks like this:
dial-peer voice 55555551 voip
 preference 1
 destination-pattern 5555555
 voice-class codec 1
 voice-class h323 1
 session target ipv4:192.168.1.1
 dtmf-relay h245-alphanumeric
 fax protocol t38 ls-redundancy 0 hs-redundancy 0 fallback pass-through g711ulaw
 no vad

In the SR140 T38 confgi:
 media_renegotiate_delay_outbound: -1    < this is key!>

Even though we switched to xmedius, I believe that the changes you suggested would have fixed our issue as well.
