MGCP T38 FAX config

does anybody have a working config for a ios gateway running MGCP with t38 FAX support.

Should i be programming anything on th ecall agent for t38 support to work ?

My client has a IOS gateway MGCP controlled and VG224 gateway controlled by MGCP for FAX. Issues with fax transmission. Callmanager 4.2

Re: MGCP T38 FAX config

Hi,

This command does not need to be configured inside a dial-peer. You need to put it directly in the config.

It is only needed on the ios gateway where the faxes enter trough to get to your fax server. In your case only the vg224.

Hi,

Don't think it is supported, check this url:

http://www.cisco.com/en/US/tech/tk652/tk777/technologies_tech_note09186a0080159cf3.shtml

you can do cisco fax relay or pass through.

Re: MGCP T38 FAX config

Hi Aizhar

I'm a little confused, i understand that the T38 when using MGCP is not supported on Callmanager V5.1.

if i want to use Cisco FAX relay what do i have to configure. The outside gateways are setup and configured for MGCP. Would i be better seting up the E1 gateways for H323 and the VG224 with H323 ? if i leave the gatewasy on MGCP and change the vg224 to H323 what fax protocol would be used?

Any help would be great.

Re: MGCP T38 FAX config

Hi,

Indeed t38 fax is not supported in callmanager 4.x when using mgcp.

You need to set up an ios gateway as h323 gateway.

In the config, you need to add :

voice service voip

fax protocol t38 ls-redundancy 0 hs-redundancy 0 fallback cisco

Hi

Thanks for the info, does this command work for all dial peers. And i presume thsi is also required on the VG224 gateway ?

Re: MGCP T38 FAX config

Here is a better solution, look at XMediusFAX for your fax server. It supports T.38 with CCM 4.1 using H.323 or CCM 4.2 also supports MGCP. This IP fax solution is great, CTDP certified, is easy to install, setup and works well. Check partner Central for more details or www.faxserver.com
