style='font-size:10.0pt;font-family:"Tahoma","sans-serif"'> Getting ready
to finally convert PSTN trunking from some larger Nortel PBX systems to Cisco
gateways. Up to this point we have been using PRI tie lines between the PBXs
and Cisco gateways and routing PSTN calls via the PBX. On the PBXs we are
using various PSTN PRIs using primary and backup D channels and in some cases
NFAS. Can these connectivity options be recreated in a Call Manager
6.1 environment or will I need to order new PRIs with individual D-Channels?
Can not seem to find any info on this<o:p></o:p></span></p>
