I am an Asterisk newby, and I cannot seem to get Caller ID information from our T1 line. When calls appear at the phones, they say the call came from "asterisk" and unknown number. I know how Caller ID information is passed on an analog phone line (between the rings) but with a T1 line, I don't know technically how it is done. I don't see the caller's number in the CDR records either. What am I missing -- where shall I search? -- Scott Nelson Thermeon Corporation - St. Louis

That's the difference with a PRI circuit--you get the caller name as well as caller number.
Scott, I'm new to *, but I know T1s pretty well - most likely you're not getting that information with your wink-start trunk. Most of the time, you're only getting the DNIS (dialed number), not the ANI (calling party). Here's a Cisco doc that explains CAS circuits a bit: http://www.cisco.com/en/US/tech/tk652/tk653/technologies_tech_note09186a00800e2560.shtml Eric On Thu, 17 Mar 2005 13:17:37 -0600, Scott Nelson <sbn@thermeon.com> wrote:> I am an Asterisk newby, and I cannot seem to get Caller ID information > from our T1 line.

-----Original Message----- <snip> I know how Caller ID information is passed on an analog phone line (between the rings) but with a T1 line, I don't know technically how it is done. CallerID is not normally available on a T-1 but is more designed to come in on a PRI. Look into featd and featdmf signaling in Zapata.conf to get ANI on a t-1 span.

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.
