Subject: [Asterisk-Users] Provisioning CO lines

[Steve Lane]

Or you could try a bandwidth broker that will find the quote to suite
you from a database of carriers in your area and give you the best
price. I get my T1s here in Dallas, TX for around $400 including the
local loop. That includes the voice channels and everything included for
12 voice channels and 12 data channels.

I'm brand new to asterisk but not to T1s so here's my bit to contribute.

Each local telco {be they ILEC or CLEC} is different depending on their 
CO switch and the software options they've purchased for it.

In Alaska, the "break-even" for switching from POTS to T1 is about 13 
trunks.

Your telco will offer "regular T1" and/or ISDN-PRI.  Up here the
tariffed 
rate on ISDN-PRI makes it as expensive as POTS lines.  We lose 
callerID if we go to regular T1 but that's because the local telco
hasn't 
spent the money to upgrade their switch.

Best thing to do is tell your sales rep you want quotes for 10-24 trunks
in 
PRI-ISDN, regular T1 and POTS.  This can be like pulling teeth but it's 
what you need to make the best buying decision.  Then you can decide 
when/if it's time to jump to digital and what kind to go for.
