That is an interesting question as Ironically I am having a bit of an issue here with a UK Mobile Link connected over DPNSS
It's with regard to Mobile dialling over this link to a set thats CallForwarded Back out over this link to another Mobile.
Now having looked at the prompts in CDB and the Route, I thought initially these prompts may have been effecting this and confirming they are set to:-
TNDM 15 (CDB)
TROMB YES (Route)
The mobile caller is ending up on the Switchboard?
When I capture the DPNSS Monitoring, its if the DPNSS signalling over this link isn't seeing or rejecting the CallForward conditions?
Any DPNSS guru's out there?
Cheers!!
