Callback to PTT Number

[EFIGUEIR]

Do someone knows how to configure MD110 to allow to do a external callback to a public external number, using the ISDN to PTT.

What we would like to do is to when some call to a supplier/ customer was busy we would activate the CAB facility and when customer/supplier releases the call MD110 BC10 would do automatically the call. Nortel PBX does this.

I'm chasing for this since 1998, and the Ericsson always deny that this is possible.

Do you have a homogenous network ?
If so , automatic callback from trunks is a trivial feature.

If network is not homogenous , I doubt that even Nortel can manage it .

Or do you mean something else ?

We would like to do this to the Public ISDN Network, not on our internal network. Is this possible.

I don't think this is possible.
How do you know that Nortel does this ? Do you have concrete setup of configuration and which scenario in which they do this ?
