Is this a router that you use for voice / data or what ?

Without knowing a bit more about your environment it is difficult to solve the problem: for example it would be helpful to know what platform this is happening on and some details of its configuration.

I take it from the output that you posted that there is an incoming PRI which is receiving the call and that something about the incoming call is incompatible with the way that the router has been set up. My first guess (without knowing any more details) would be that it was an analog call coming in which can not be handled by the digital facilities of the PRI.

The router is configured for data.

[Richard Burts]

derek

So what is the possibility that the incoming call is analog?

[drsejjuko]

The incoming call from the other end is supposed to be digital,the platform is 3700 series and the image on it is 12.4 IOS.

[Richard Burts]

derek

So can you find (and post) some details from the 3700 that can confirm (or not) that it is placing digital calls?

Hi,

can you post debug isdn q931 from the router that is placing the call ?

[acharyr123]

Hi,

I am also placing similar issue at my site.Plz find the debug output & suggest..

[smothuku]

Hi ,

Cause i = 0x80D8 - Incompatible destination

Ceck the remote end ISDN number.

The configured nmber on remote end may not be correct...

can paste both routers config.

Thanks,

Satish

Hi,

This has been sorted out, the problem was remote end isdn switch type .
