We have an system running with different SIP trunks on the same PBX (different countries). The SIP trunks are terminated locally. We have configured COR in a way that the devices call through the SIP trunk based on their location. In the ARS we make use of "Route lists". This works fine also when the users transfer calls. What we are facing is that when a user regardless of her/his location enables "call forward always" option to an external number always the first configured SIP trunk is used.
Is there any option like in COS for example that makes it possible that the same SIP trunk is used? Or a trick in the ARS forms. For now we have created a static route with another out dial number instead of the default 0 as an workaround.
