[Asterisk-Users] Caller ID on E&M Wink

[mattf]

With a RBS(Robbed-bit) T1(in other words, not a PRI) the CallerID(Called
ANI) is sent in the digits and come across in Asterisk as part of the
extension. It is not standard, you do need to ask for it to be enabled and
you usually have to specify how you want it.

A standard way of receiving ANI on a RBS T1 is this: *NXXNXXXXXX*DNIS where
NXXNXXXXXX is the callerID and the DNIS is the last 4 digits of the number
the caller dialed.

There is no option of receiving callerIDname with RBS T1s but you do get
that 24th channel to use for voice that you don't get with a PRI.

Hope this helps,

MATT---

With an E&M T-1, I think CallerID number comes across as DTMF digits. 
That's the difference with a PRI circuit--you get the caller name as 
well as caller number.
