Re: ISDN BRI for VoIP in 26xx

The card you are looking for could be the one- or two-port T1/E1 Multiflex Voice/WAN Interface Cards (VWICs) in the High Density Voice Network Module (NM-HDV)' .

In Cisco IOS. Software Release 12.0(7)T, NM-HDV was introduced to support voice connectivity on T1/E1 interfaces from Cisco 2600/3600 series IOS gateways to a PBX or the Public Switched Telephone Network (PSTN). Signaling support on digital and analog interfaces on the Cisco 2600/3600 series gateways now includes BRI, Foreign Exchange Office (FXO)

The above statement is justified in the document given below:

You need a VIC-2BRI-NT/TE module. This card will interface to a PBX as a Network side device, and supply line power to bring up the link. Have a look here for more details -
