VG200 - using FAX on FXS port

Howdy all,

Is there a CCO bug saying that MCGP will not work for FAX using an FXS port on a VG200 gateway. Is it true that you have to use H.323 for fax to work ??

Need clarification ... pls...

You can use MGCP. Make sure you are running the latest 12.1(5)XM version, and make sure you enable the global command mgcp modem passthrough voip mode cisco although in some versions the syntax for this command is slightly different.

Re: VG200 - using FAX on FXS port

I saw your message of Oct 16, and you say it is working "fairly well" with the "mgcp modem passthrough voip mode cisco" command. Are there known problems with this config? I opened a TAC case against this issue and was told that MGCP support for fax relay and fax passthrough would not be available until 12.2(2)XN. I have several VG200's running h.323 currently due to VG200 lockup problems when running MGCP with fax that I would love to be able to change back to MGCP.

Thanks,

Pat

Fax relay and/or fax passthrough are not supported for MGCP on the VG200 until 12.2(2)XN.
