We have an Extension (201) that will be forwarded after 10 sec. This is fowarded to a outside mobile number. We have 2 Outbound Rules (Rule1 and Rule2) for 2 different SIP Trunks. (This is separated by Groups with Extensions.) Ext. 201 is member of the Group for Rule2 Problem. When the Caller is forwarded to the mobile number it is forwarded over Rule 1. Temporary Solution. I have changed the order, Placed Rule2 above Rule1. This did the trick but is NOT THE SOLUTION!
