Hi, i have a quick question (and hopefully a quick answer :) )<br clear="all">I have a customer who wants to connect there legacy PBX to a ISDN PRI port on a Cisco 2801 Router which will be connected to a softswitch via SIP protocol. I've never done SIP on VG or this type of connection, so can someone please tell me is there something special or i can just use any 2801 Voice Bundle with PRI interface. Do i need any particylar IOS? I have no idea what type is the softswitch (it's not CUCM) or the PBX.<br>
