Atlas 550 not passing CID NAM even though it is in Call Setup message

Jump to solution

The Atlas 550 is not passing CID NAM even though it is in the Call Setup message; it seems to work for less than 24 hours and then stop.

Here is a formatted dump (from the 550) that shows the Name is in the display:

This is what comes from the telco:

However,  this is what the atlas is sending to the KSU:

Any ideas?

There may be a little confusion. The name does not have to be in a separate facility IE, but it cannot be a DISPLAY IE. The ATLAS 550 supports the name either in the SETUP message or in a supplemental STATUS message, but it does have to be a FACILITY IE. The ATLAS 830 and 890 work best if the name is presented in the SETUP message (as a Facility IE).

Hi bbb,

I don't see the Caller ID Name in the trace from the telco.

It appears the Caller ID information is being presented as a Display Information Element (IE) as "IE - 28 DISPLAY" followed by the caller ID information. The ATLAS only supports Caller ID in a Facility IE. If the CID Name is not presented as a Facility IE, the ATLAS will not pass the information.

Thank you,

Patrick

Patrick,

  This has not been my experience with the 550.  I see you work with Adtran 🙂  I'm pretty sure that I have called and spoken about this issue with Adtran TS several times, and the name has to be in the setup message, not a separate facility message.  This is not the entire dump, but it is currently being sent in both the setup and a follow up facility message.

  And, oddly enough, it works for about the first 24 hours or so.  Would you please re-confirm that the Atlas expects it as a separate facility (IE 1C) message?

  Thank you!
