long delay when making outside call

[cteyul]

HI we have a neax2400 ipx. in th elast 2 weeks whenever we place an external call we get a delay of up to 30 seconds sometimes before it rings. this only happens when dialing outside lines internal extensions ring imediately. any ideas as to what is causing this?

any help will be greatly appreciated.

My first gues would be AMND might have gotten messed up. I assume you had no problem up until 2 weeks ago. You don't mention any changes but maybe some other tech who is working on the system might have made a change un-intentionally.

Do you have this problem on local, long distance and international calls?

Also, try this: try to make a call, and when you finished dialing the digits, hit the "#" key on the phone and see if that takes away the delay.

yes that is correct we haven't done any changes and yes this happens for local, long distance and international.

i tried hitting the # key after dialing the digits but it is still the same.

Ok, do a DCON (or DCONX) and monitor a phone that you can use to test with and watch the MAT screen at the same time.

Dial a number and see what happend on the screen. Ideally, this is what you would see.
-Go off-hook with the phone and see it on the screen connecting to a trunk in route 902.

-Dial a local or US Long-distance number (not international). As soon as you are done dialing, you should see your phone connecting to a trunk on the route that supposed to handle to call.

-If you see your phone connecting to the route immediately after finsihing dialing, there may be something you have to sort out with the telco.

-If there is a delay connecting to that route after you finished dialing the phone number, there will be somthing still to be checked on the switch.

But first just do the test and let us know which way it went.

ok i tried it and yes when i go off hook route 902 comes up and as soon as i am done dialing a second line flashes with route 905 and disappars then the line with the 902 route changes to the route it is suppose to use which is 29 then the delay comes.

Ok. If you can double-triple check that nothing changed on the switch, with the above test everything points towards a telco change. What hardware do you have for route 29? T1? PRI? Something else?

Contact telco tech support and complain about this problem. They will eventually have a tech working with you who can see what kind of traffic is coming from your switch to them and what they are doing and most likely with that, you and telco can figure out where is the delay coming from.
