I am using v10 SP2 of the 3CX Phone System and am having an issue when it comes to routing of calls to my mobile after hours. The system consists of 3 Yealink IP Phones, 1 T28P and 2 T22P and 2 x SPA3102s for the PSTN lines, there are no VOIP accounts. Eash SPA has a line assigned to it, Line 1 and Line 2. The problem I am having is that when there is an incoming call on Line 1 and it is out of office hours, the call gets routed to my mobile via Line 2, but when somebody calls on Line 2, the call does not get routed to my mobile via Line 1. What could be the issue with the routing?
