I am wondering if anybody here can help me with setting up the config file on a Cisco 2811 router to act as a PRI to Sip Gateway. I came across a few threads about this subject but I need to get some details ironed out. I will be deploying latest distro of FreePBX on a VM at my brother’s business. Location is still under contract for another year with two T1/PRI (46 channels) so I have to make use of it for now.
I purchased a Cisco 2811 on eBay with IOS 12.4, with a dual port vwic 2mft-t1, & 1 ATM/Voice AIM. I added a 4 port FXS card and I have a PVDM2-64 in the mail.
The basic config is described in this thread from 2012: https://community.freepbx.org/t/basic-setup-from-freepbx-to-cisco-28xx-as-voicegateway-with-pri/12846
Since I have dual t1 with 46 channels, I would need to modify that config along with changing the system specific items (IP’s, Slot Numbers, etc.)
If possible, I would also like to peel off the fax DIDs and send them to the FXO Ports and send any and all other DIDs to the sip trunk.
