PLEASE TRY LATER Error Message

[SaeedAyman]

I have a problem on a PRI line, it is programmed as a DOD line. I successfully can dial a local and long distance calls on it, but the problem with international and mobile numbers to be dialed (which have longer digits that the local and long distance calls), I get a (Please Try Later) message on the Digital phones.
Does anyone has an explanation for that?

Without knowing more history, like knowing it used to work once upon a time, I would speculate that you need to define LDPLN entries for the digit strings you will be dialing and designate routes for them. Some examples for US:

NXX-XXXX

NXX-NXX-XXXX

I don't do much of anything with international at all besides what was programmed in when I bought the switch, but I would assume for basic international you might need something like:

NX-X-NXX-NXX-XXXX

or something else that matches how the digit strings are usually dialed.

I don't remember if LDPLN access the LCR dialing rules on the 4000 or if it is a different AMO. That would be the first place I looked - in your LCR dialing rules.

My LDPLN entry satisfies the dialled pattern.
The LDP is *90-Z, so any digits after the *90 will be sent.
I also tried a specific pattern to be entered, I get the same result.
May be if anyone know the meaning of the message (Please try later) would solve the problem

Please Try Later for me usually means the trunk I am trying to send on (Cornet) is out of service, or I am getting a fast busy from the other end, or internally the station I'm trying to reach is out of service. I have 3 PRI circuits for my main trunking and have never lost all 3 of them at once, but I would assume I would get that same message if none of them are in service either.

Do you have your 90-Z routed to a known good trunk group?

Also, on my switch, 90Z would be how I would route a call if I wanted telco operator intervention. Isn't 9-011-Z the equivalent for international? I don't know that much about international dialing, sorry....

I am in Egypt
the *90 is only the switch access code.
The trunk is being tested successfully with the local and long-distance calls, the problem is with the mobile or international, which both have larger number of digits to be sent (I am just thinking loudly, I do not know if the number of digits is the problem, may be the richt must have a certain number of digits? I don't know)
