Moises, Thanks for the reply. I did do that and FS core dumped when I cycled loopback in my mux on several T1’s so I thought that I had some configuration errors. I am using 2x4 port Sangoma PCI-Express cards. We may have to investigate mod_freetdm from the recent development effort we invested in. We are using: FreeSWITCH Version 1.2.8+git~20130410T033224Z~8dd4c8f9f1 (git 8dd4c8f 2013-04-10 03:32:24Z) Regards, Brian C.

I have it working with one port but what is the proper syntax for multiple Sangoma RBS T1 ports in freetdm.conf and freetdm.conf.xml? The installation scripts wancfg_fs and wancfg_dahdi put them in the PRI type notation and cannot find how to rework for multiple RBS. Here is a working stripped down to only one port. This is after going through script and only setting one port as used.
