trunk group isdn and cas

Hi voice team

I have a E1 ISDN and E1 R2 in the same router, the E1 R2 have the channels  1 to 15 for incoming calls and the channels 17 to 31 for outgoing calls, and the ISDN it's for incoming and outgoing.

For the outgoing calls i need the calls always going to the E1 R2 and when the all the outgoing channels is busy the calls going to E1 ISDN.

Now  the configuration is with preference in the dial-peer, but i need using some like trunk group.

I try to make a trunk group but i cant add the ISDN channels after add the cas channels. the gateway send to me this message and not add the channels to trunk group.

How to fix this?

Re: trunk group isdn and cas

As the message is cleary saying, cannot mix ISDN and CAS in the same trunk group.

You will need to configure multiple dial-peers with the desired preference
