Disconnect PRI-PSTN: 0x80A9 - Temporary failure

hi,

When a place a call from IPPhone to another IPPhone but to the DDI, the Gw drops the call, traces shows "Cause i = 0x80A9 - Temporary failure" and if i repeat the call after few seconds runs properly.

I have make debug isdn q921 to to verify layer 2 events for the isdn, and

debug mgcp errors

debug mgcp packet debug mgcp errors
debug mgcp packet

but I can not see where is the problem because MGCP is correctly configured and other calls go ahead, it looks like only a numeration range, here is traces from Gw

Disconnect PRI-PSTN: 0x80A9 - Temporary failure

Hi,

Does the call go out and back in via the same gateway.

Can we see the

debug q931 of the call going out then back in

Alex

Thanks in advance for your answer, the problem was with de voice port:

0/0/1:15        31  xcc-voice   up    up     none     none     y

After restart that voice port 0/0/1 is running properly althought i still dont know if it have been a phisically problem or whatever...

I only have one question more, when I place a call my calling is my IPPhone, but if I repeat a call, my calling in traces change to the head line, and the Type change too, why??

1st test:

Calling Party Number i = 0x0081, '9158527XX'  -> My iphone

                Plan:Unknown, Type:Unknown

        Called Party Number i = 0x80, '91504XXXX'

                Plan:Unknown, Type:Unknown

Calling Party Number i = 0x0183, '914816252'

          

2nd test  (the same IPhone to the same called number few seconds after)

Calling Party Number i = 0x0183, '9148162XX'  the head line¿?????
                Plan:ISDN, Type:Unknown
        Called Party Number i = 0xA1, '9150492XX'
                Plan:ISDN, Type:National   -> this have changed

Thanks!

Hi Alex,

We are seeing the "Temporary Failure" sometimes when the call goes and back via the same gateway? Is this normal? What is the cause on this?

Thanks.

Michael
