MGCP using modem passthrough

Hello,

I have a VG224 that a customer has and has troubles connecting with modems. Below is the config using MGCP, any ideas why users have to try to reconnect multiple times? Thanks.

mgcp

mgcp dtmf-relay voip codec all mode out-of-band

mgcp rtp unreachable timeout 1000 action notify

Re: MGCP using modem passthrough

If you need to configure fax pass-through to work with Cisco CallManager (CCM), you must use the modem passthrough nse command. The fax protocol pass-through command does not work with CCM, which relies on NSE information. Refer URL
