[cisco-voip] How NOT to send Suspend on ISDN?

[Kelemen Zoltan]

We have Euro-isdn, or primary-net5 here in Europe, and I assume it 
wouldn't be functional otherwise anyway. Most of the calls do work 
through this switch.

The switch I'm connecting to seems to be a Huawei SoftX3000 according to 
the traces I received from the provider.

Also, according to this trace, the remote caller will disconnect with a 
normal call clearing as a response to the SUS message transmitted to 
them originating from my gateway.

So. any ideas?

thanks,
  Zoltan
