[asterisk-users] e911 Signalling
Hi,
We've got a dedicated T1 with two trunks running into our ILECs
selective router for 911. Split out of the T1 into two MF CAMA trunks
on ILEC side.
I'm trying to use asterisks e911 signaling, but I'm having trouble with
the dial command. (== Everyone is busy/congested at this time (1:1/0/0))
I'm missing something and I'm thinking it has to do with the hookstate
of the dahdi channel.
If anyone has a similar situation and want to provide some guidance, I'd
sure appreciate it.
Thanks!
Adam

Well, good news, it was the telco side. They had their ports disabled.
I ended up having to use signalling=fgccamamf.
