I would like to configure dtmf out of band for an issue I may be having on an MGCP gateway. The gateway, however, does not have dial-peers. MGCP gateways that are configured via cluster used to have dial-peers numbered in the 9XX range, I believe, but I've found that in more recent revisions that this is not the case. Does anyone know how this has changed and what recourse I have for this issue?

There's an MGCP command;
mgcp dtmf-relay voip codec all mode out-of-band
That appears to be an equivalent. Is this what it is for?

Hi,
that command will do that trick.
thanks

Hi There
This may or may not be applicable,
taken from another forum post:
CSCso87127 in-band DTMF leakage of 40-50msec observed when using DTMF relay
May be worth checking out.

In all circumstances, the gateway will send a NTFY with D/
This command allows for it to advertise the capability to CUCM and for CUCM to know to forward it on.
If you use 'ccm-manager config' this is an automatic configuration.
You can use 'debug mgcp packet' and you should see NTFY messages with the line D/1, D/2, etc in it.
