I have a customer with a VG224 running MGCP to Call Manager 3.3.4. They have one brand (Kyocera) of Fax machines that will not work on the VG224 but works fine off an ATA-186. It fails to set up during the Handshake. Any ideas of paramaters that can be changed to make it work? Call Manager has a 3725 with a PRI for the external Gateway running MGCP.

It might be some particular command on the VG224. You may like to verfiy your config with the following sample config.

I had looked at this example but it does not reference any MGCP commands. They have other brand Fax machines on it that run correctly. Are there specific commands for Fax Pass-Thru with the MCGP command set?
mgcp
mgcp call-agent 10.4.1.11 2427 service-type mgcp version 0.1
mgcp dtmf-relay voip codec all mode out-of-band
no mgcp timer receive-rtcp
mgcp bind control source-interface FastEthernet0/0
mgcp bind media source-interface FastEthernet0/0
!
mgcp profile default
!
!
dial-peer voice 1 pots
application mgcpapp
port 2/0

System image file is "slot0:vg224-i6s-mz.123-7.T.bin"

Hi,
we had similar problems with 2651 and AIM-Voice modul (we used H.323)
and VG248.
Later we changed in the PSTN Gateway (2651) the modul to NM-HDV with MFT-E1 => and it works !!!
With V.34 Fax-machines (or "Super G3") only pass through is working !!
Don´t use Fax Relay !
concerning your question: MGCP and Pass through
you need follwing commands:
no ccm-manager fax protocol cisco
mgcp modem passthrough voip mode nse
mgcp modem passthrough voip codec g711alaw
and IOS 12.2.11T ->

hi paul,
Maybe try to use "show ccm-manager"just to verify that VG224 see the CCM.Try to add "ccm-manager mgcp" from your config.I experience same problem with you though i use VG200 with vg200-i6s-mz.122-24.bin image.Hope that would help.
