[Asterisk-Users] what do I ask my provider for when using e&m_w and a T100P?

[Claudio Caballero]

I struggled with this issue too. In my case, it was for the voice part of
a combined T-1 line from XO, which is coming out an Adtran 604 router as
the CPE. The secret sauce for me was to configure all 24 channels, but
then only use the first 6 (since that is what we ordered) in the dialplan.

So, here are the configs:

zaptel.conf:
loadzone = us
defaultzone=us
span=1,0,0,esf,b8zs
e&m = 1-24

zapata.conf:
[channels]
language = en
context = default
transfer = no
group=1
signalling = em_w
channel => 1-6
group=2
channel => 7-24
