Hi, I have a question, is it possible make that the UCM6xxx it can detect if una line is occupied? It is for the outbound routes, I want to make that the ucm be able to choose one the available trunk line
The UCM is a PBX. The intent of the PBX is to handle calls, both inbound and outbound, without the need for human interaction. You can establish outbound rules that may accommodate your need, the directions of which can be found in the admin guide on the GS website.
If you want to truly monitor the lines such as was common with older key switch systems, do a forum search or look as SCA (shared call appearance).
The UCM will always know what FXO ports are in use, so look at the rules and the failover aspects…you can get pretty creative.
