Hi,
We currently have a PRI link to our gateway which sends calls to call manager 6.1. We want to add two more basic rate ISDN connection to the same gateway with different number rages. meaning we will have three different number ranges connecting to the same gateway and call manager. is this possible?
How do we go about this?
my idea is to plug in the ISDN basic rate module 2BRI-NT/TE to the 3845 gateway and plug in the ISDN NTs, then configure voice peers with the call manager as the session target. then create phone profiles on Call manager with this new numbers (exension mobility is not required for this)
please help.
Regards,
Regar

hi Rager,
yup you can connects multiple bri cards and it works fine .. we are also using the same in our enviorment .. infact we are doin this for 7 clients .. means 7 different lines are connected to the same gateway and they make their calls from their own phones infact some phones are sharing 2 lines with different lines.. this is just add gateways and give proper CSS and partitions.. if you need help feel free to write..
if you like this then plz rate this also

Reger,
make sure to verify that there are sufficient DSP resources on the gateway. use the DSP calculator, http://cisco.com/cgi-bin/Support/DSP/cisco_prodsel.pl, and compare the results with what is currently installed on the router.
