Mitel 3300 Quad BRI Busy-Call drop

[OldMatey]

Hey,

Wall of text follows, sos but I wanted to give as much detail as possible.

I am installing a 3300 CXi in Ibiza. I have 3 BRI lines coming in to a Quad BRI Card. All 3 are green lights and say idle when I do a stat. The first BRI circuit is my clock source and when I do a DTSTAT the link is active with no losses/slips.

I can Dial out over these circuits and the call connects fine and speech is clear. Then about 20secs - 2 mins into a call it displays busy (with wait above the third button under the display) and the call drops. The same happens with incoming calls. After this has happened the trunk remains unceasable for 10-30 secs.

Doing a CCS Trace you get

Date RI31 DPN 6 CRM/CIM ;7;*58#

Off the top of my head the *58 means unspecified something or another (Haven't got my CCS trace book with me). This is an incoming message so I am sure it is something to do with the local PTT, but they are having none of it. (still trying to get them to come out and test he lines)

Anyone have any ideas or experienced something similar?

Thanks

Old Matey

i think you gotta look at the ;7;. this means congestion/route busy

I can only imagine that somehow you're getting a busy signal from your local telco.
does this happen on all the links..

Thanks for the Reply. It happens on all the BRI circuits. The ;7; makes sense because its says busy when the call drops but the *58# doesn't give me any more info about why.

I have managed to get the local PTT to come out and have a look they should be here about 9:00am so hopefully they will be able to give some answers.

the why is the 7. your get busy from the exchange. maybe local PTT guys can put an ISDN tester and try the scenario again?
