I have modems connected to a VG200 w/12.15xm4 using MGCP w/CallMan 3.12a. Theses are going out a Pri on a different VG200 running H323. The modems will connect for about two seconds (after negotiation) then drop. Any suggestion would be appreciated.
Modem passthrough and modem relay are both planned for the VG200 platform but they are not yet available. If you need further information or need to present a business case to get this implemented more quickly you should contact your account rep.
I know that the command must be entered in order for fax relay to work. But for modem passthrough/relay I have no idea. You might have better success using 12.1XM software, but still everything I have seen indicates that modem passthrough/relay is planned but not yet offered on the VG200 platform.
Fax relay should work for you in MGCP mode. You should use the latest 12.1XM code currently, and make sure you enable the command mgcp modem passthrough voip mode cisco. I think in different versions that command actually changed syntax.
