I am in Nairobi Kenya. Here we use ISDN Basic-net3 and my problem is that most of the telco switches here deactivate Layer 1 when there is no active call.
When I try to initiate a call by using the ISDN test call command I get an error to the effect that B channel is not available.
The only way I can initiate a call is I first call the line then and then disconnect. Then I have about 5 seconds to make a test call and pings are successful. How do I make the router initiate a call when layer 1 is deactivated.
the debug isdn q921 out has nothing till a call comes in.
I also understatnd that European ISDN switches deactivate Layer 1 when there no active call. I dont have a problem with one of the switches, coz it does not bring down the line when there is no active call.
Thakx in advance
