I have 2 routers (cisco 2621XM and 1841) and want to use one of them with the ISDN card (WIC 1B S/T) for PSTN Breakout.
My idea is to create a SIP gateway on the router and then the ISDN card to the PSTN and use it as a gateway of the SIP devices.
Basically I have a OCS R2 infra-structure and i want to establish a SIP trunk between the Mediation Server and tyhe router and then create a few translations and dial peers to break out to the PSTN.
Is this possible ? Where can i find some examples to build a config ?
Thanks in advance
