Waiting-for-Line problem

Waiting-for-Line problem

I am using IPO 500 (4.1)with T1 PRI . My problem is "wait-for-line" is kept on appearing on the phone display and giving busy tone after that. It happened even though 23 channels are in service-idle. Anyone who encounter this problem?


RE: Waiting-for-Line problem

One site I had when I upgraded I had to add an entry in ARS


it doesn't make sense to me but it worked.

RE: Waiting-for-Line problem

Double check your system short codes, ARS entries and line group assignments

RE: Waiting-for-Line problem

I have had this problem serveral times.  Who is the carrier providing the PRI?  Are you using NI2 or 5E?

RE: Waiting-for-Line problem

If you have analog lines make sure they are set to a different line id.

RE: Waiting-for-Line problem

I have short codes configured:

Verizon is the T1 provider and using NI2.

I also have analog trunks with different line ID. Still I encountered the problem.


RE: Waiting-for-Line problem

More info needed

What line group/ARS doesn that SC go to??

RE: Waiting-for-Line problem

With Verizon being the Carrier I would think that your problem is not the same as mine.  4.1.9 & 4.1.12 gave me problems with certain carriers switches when running NI2.  We could receive incoming calls but not make outbound calls.  We would get waiting for line.  The quick fix was to change to 5E.  This fixed the problem.  Give it a try.

RE: Waiting-for-Line problem


Line group 0 and I only have 1 trunk the PRI.

RE: Waiting-for-Line problem

I just dealt with the same issue on IP500 with 4.1(12) and "new" PRI card.  

I saw cause code 99 in my traces when calls did not go through.  The CLEC tester said that they saw protocol errors on their soft switch when we tried to dial.  

We got it working with either 5E or DMS for Switch Type under Line and PRI.  

Good Luck,

RE: Waiting-for-Line problem

I have had this happen on ramdom extn's and was due to the system returning "waiting for line" when an invalied number was sent to line. The system was running a low level of 4.1 software and we were advised by Avaya to upgrade, this resolved the issue.

I'm not sure for the sofware level and will check this tomorrow.
