Our FreeSWITCH setup has an existing T1 using RBS to talk to a digital
modem pack in a Cisco 3845. I'm interested in changing from RBS to
ISDN. I changed both sides, restart things, and see FreeSWITCH report:

I've attached the configs and Cisco debug below. This is using the
native ISDN support in FreeSWITCH with a Sangoma A104d on FreeBSD 6.4.
I unfortunately don't currently speak ISDN (though I'm starting to pick
up a little as a result of this exercise) ... suggestions / hints regarding
what's going on and how to resolve it would be welcomed.
