ISDN BRI and CCM issue

HI all,

recently i tried to configure an ISDN connection with CallManager and it works fine but i'm stuck in something and thanks for ur previous posts by the way

I have a range of number from my SP like:

from 555501 to 555509 and i want that a predefined IP Phones like extension 4000 to use a specific PSTN number for inbound and outband Call and with an anology from the FXO conf i set up the:

Destination-pattern 9T for outband call


Connection plar opx 4000 for the inband

BUT with the BRI how it can be done?

Thanks in advance for all

Re: ISDN BRI and CCM issue

You can configure the BRI either as MGCP or H323

If H323 then configure a dial-peer pots with direct inward dial then a voip to fwd the number directly to ccm

If MGCP Just configure proper CSS and incoming settings for Voice Port

Re: ISDN BRI and CCM issue

thanks for your reply but if the user want to use a specific number as his personnel PSTN number i mean for example if DN 4000 want only to use the PSTN number 555022 as the outband call ?
