AS5300 ISDN Problem

After getting incoming call from PRI, i get the the error below.

Is a problem only in "Preffered" bit in Channel ID

or in something else?

As i know network side (Telco switch) can set only exclusive bit if this is primary-net5 swicth.

Re: AS5300 ISDN Problem

Hello,

I had the same problem with an AS5350 using IOS from 12.2.13T to 12.3.3a.

Check this bug out :

CSCdz87218

Symptoms: A router may start dropping calls that have the "0x2C" cause code. The cause code indicates that the requested circuit or channel is not available.

Conditions: This symptom is observed on a Cisco AS5300 that has free digital signal processor (DSP) resources.

Workaround: There is no workaround.

Even if on the bug toolkit it says that 12.3.3a is affected, after upgrading to 12.3.3a it worked ok for me... or you can just go back to 12.2 XB :)
