How can tell which trunk a call comes in on?

[LesD]

I have got several sip trunks with their own DIDs. I am using an Aastra 6757i phone.

When a call rings in I want to know before I pick up, which line the call came in on.

From the log I can see that the correct incoming route has been identified. How can I get that showing on the phone?

Or is it possible to get a different ring pattern based on the trunk?

Thank you very much. Working - though where the call is from someone in the phone's address-book then those details overwrite the prefix.

Thinking again about my comment, I think it actually makes sense (or at least is not a problem) where the trunk ID is lost when the caller is in the address-book.

The need to identify the incoming trunk is generally to give an idea as to the type of the incoming caller. If the caller can be individually identified then the trunk being used is not very significant.
