We want to make a DDR between one of our customer. In our side we use 3640 router with bri interface and other side has as5300 with pri interface.
As5300 also using for async call in and also callout without any problem.
For isdn this is the first time for them.
If we started DDR form 3640 there is no problem to established session but in our case they have to Dial in us. So we tried start dialing from As5300 side but in that case it wasn't completed succesfully. They got casue code:0x81D8 and no message appeared on 3640 router during this failure period.
