Is $rv_lineid A 'constant' For Each Physical Line?

[Guest vgfan]

I'm running T1 lines and I understand the $RV_Lineid is a unique identifier for a line which may not correspond to the line sequence (i.e. the 19th line out of the 23 lines of the T1 will not necessarily have $RV_LineID as 19, but may be another number, say 39).

 

My question is that if this ID is unique on the 'phyiscal line'? I assume that if the same physical line has dropped a call and afterwards takes up another call, the same ID (39) will be allocated as the RV_LineID. Also, I would like to know if the same allocation is valid (e.g. the 22nd line being allocated ID of 39) can remain after vg re-start or server restart.

 

Thanks for the clarification. It's very important to understand this as I'm trying to build programmes to monitor and track exact utilization of each 'physical' line (I know I'm not using the correct terms as a T1 (with 23 lines) has only 1 physical line. Anyway, I hope my question is clear.

 

Also, what's the difference between $RV_Lineid and $RV_deviceid?

 

Thanks a lot for your advice!

Correct.

Yes. Calls arriving on the same line will have same $RV_LineID.

Also, I would like to know if the same allocation is valid (e.g. the 22nd line being allocated ID of 39) can remain after vg re-start or server restart.

Yes, it will, unless communications related hardware in system is changed - then different IDs may be assigned.

Also, what's the difference between $RV_Lineid and $RV_deviceid?

No difference. Same value is stored in both. $RV_DeviceId is scheduled to be removed from documentation and will not be supported eventually - use $RV_LineId instead of $RV_DeviceId.

 

In VG for Dialogic you can use $RV_LineStatusListPos to get the position of the line within the VG's 'Line Status' listing.

Thanks! It's very helpful indeed!

 

I'm not aware of the $RV_LineStatusListPos. Is there a set of Result Variables for Dialogic (I don't seem to see them in the Help files.) Please advise how I can get more info on them.

 

Thanks!
