Hello all
What I'm looking for is some plain speaking advice on ISDN.
Currently using 4 analog lines connecting via a four port TDM400P FXO
card. We need to physically move our installations, and on requesting
the analog lines be moved - our telco (BT) is suggesting we replace our
analog lines with ISDN2. We would have 3 x ISDN2 connections, giving us
six voice channels. They've even offered us free installation of the
lines (as opposed to a £560 charge for moving the analog lines!)
BT are sounding desperate! (And why go from 4 channels to 6?) Also watch
out what they tie you in for - I suspect they'll offer the free
installation if you sign up for a 5-year contract. One of my clients was
offered that recently...
What hardware would you recommend in the Asterisk box? I don't mind
admitting I'm a newb and a lot of the info I've found is over my head.
I've been looking at a TE410P - would this achieve what I want which is
to connect the 3 ISDN2 connections, giving me six voice channels?
Same hardware you currently have, but with an ISDN2 card rather than
TDM400.
I use the mISDN drivers, and for the most-part they seem OK. Last one I
bought was an openVox B200P from Voipon.co.uk. You'd need the B400P for 6
channels (3 ports)
Assuming the TE410P is what I'm looking for (or an equivalent -
suggestions?) what are the basic points for what I would need to change
in my current config?
Compile/install/load the mISDN drivers and then add in the configs. It's a
bit fiddly, but seems to work OK. I did have some compile issues with the
latest mISDN drivers though.
Or port it into VoIP and wave at BT ...
