All the current calls hang-up when I make a Dial-Pattern change.

When I make a Dial-Pattern change (insert, update) all the current calls hang-up !!!

Is this a bug?

I have Call Manager 3.1(2c) installed and a Cisco3640 with a NM-HDV-30(E1) as a gateway to the PSTN.

Re: All the current calls hang-up when I make a Dial-Pattern cha

You can work around this by creating a route group in CM, even if you only have the one gateway to the PSTN. Add your single device to the route group. Create a route list which includes your single route group. Point your dial-patterns to this new route list. Future modifications to your patterns will reset the list element rather than the physical device and should not interrupt your calls.

Re: All the current calls hang-up when I make a Dial-Pattern cha

Bill,

The 3640 router was set-up as a H.323 gateway, not MGCP gateway. As far as I know, I can´t add any H.323 gateway to a route group.

The reason I set-up it as a H.323 gateway is due that by now, the E1 PRI R2-modified (mexico) doesn´t work with H.323

Which other solution /work around can I apply?

Tim is correct in his post below. Well worth the effort to set it up this way.

We have 20+ H323 Gateways, all are configured using route groups.

route pat --> route list --> route group --> gateway

It might seem like alot to configure for one or two gateways, but it's worth it.
