ISDN PRI

Hello,

Just want to check if this can be done.

I have a cisco router connected via ISDN PRI to a PBX.

router---ISDN PRI---PBX

I want to group the channels on the PRI.

Channels 1-15 will be specifically used for incoming calls to the pbx, and the rest of the channels to be used specifically for outgoing calls from the PBX.

Sample configs will be appreciated.

thanks,

Re: ISDN PRI

You can use pri trunk groups to do this -

!

controller E1 0/0/1

framing NO-CRC4

clock source internal

pri-group timeslots 1-31

trunk-group Inwards timeslots 1-15

trunk-group Outwards timeslots 17-31
