Re: Problem with MGCP T38 FAX Config

If looks like the Fax server do not receive the whole dialed number, making the Fax server unable to know where to point the call to.

Re: Problem with MGCP T38 FAX Config

You need these commands:

mgcp package fxr-package

mgcp default-package fxr-package

Re: Problem with MGCP T38 FAX Config

Hi guys,

I also have a similar config with 2 vg 224 behind the routers. My problem is that I receive only half a page, no matter how many I transmit.

I put the two commandsin but they did not

solve the problem.

Does anyone know why this is happening?

I run CM7 with 12.4(24)T on the rouuters.
