I have a problem and I'm not sure how to solve it. I try to explain. I have a UC540 with severals SPA514G and everything works fine.
Now we have added a sip trunk in the UC540 and it also works well but the problem is as follows, the sip tunk has 6 channels, so 6 calls can enter simultaneously in the worst case. Well, the problem is that the SPA514 only allows 2 calls per line and if there is a third one, it appears that the line is busy.
As I said, I only setup one of the 4 possible lines configured, and I can not assign the same extension in the 4 four lines.
Can someone help me on how to get more calls in an SPA514G IP phone simultaneously?
Hello again, I think that I have found a solution. When I register a line of my SPA514G in my UC540, there is a opcion to forward call to another extension if the line is busy. Therefore, I will register the four line of my SPA514G, 210, 211, 212 and 213. Each line support 2 calls as maximun. If there is a incoming call, I forward call always to extension 210, but if the line is busy, I will setup the option "Call forward busy: " to extension 211. If I use this filosofy, my SPA514G could receive incoming calls up to 8 as maximun.
