[Asterisk-Users] DID Trunk Lines and Caller ID

[Tim Thompson]

I agree w/ Michael...if you've got 14 one-way Trunk Lines, you should be
able to get a PRI for the same cost they are paying for the 14 Trunk
lines, and then you will get 23 in/out lines and DID and all the other
bells and whistles for those lines.

It will also save you the cost of a Channelbank since you'll be able to
plug it directly into your * box.  8-)

Some long distance providers provide the information on the channel,
usually as *DNIS*ANI* or *ANI*DNIS*... I currently get something like
*16665551212*17775551213*.

It's not as slick as PRI, but it's often a lot less expensive.
