I have an older non Cisco pbx that only accepts analog lines. We are planning to upgrade the phone services to SIP because the local carrier sucks and wont replace their lines to the location. While I have programmed the SIP trunks going to a newer pbx that does the registration to the SIP provider, I havent done anything with programming the FXS card or having the 2951 do all the registration of the trunks itself. Can anyone out there provide me a direction to go, other than upgrade the PBX (that is planned for late next year).
Thanks in advance,
Mark
