Hi! When I call from 100 (FOP2 extension) to 333555 (external num via sip trunk) in FOP2 I get 2 situations
1. when phone 333555 is ringing, button 100 looks like this

100
333555

Its good.
2. But when 333555 is answering, button 100 becomes

100
100

I.e. exten num and calling number are equal. Looks like 100 calling himself.

This happens only if I call to external numbers. All works fine If calling between FOP2 or internal sip extensions.
In log I get

<- CallerIDNum: 100
<- CallerIDName: test 100
<- ConnectedLineNum: <unknown>
<- ConnectedLineName: <unknown>

Thanks! Now works great!

The problem is not solved at all. When operator calling to external number by phone, all works fine. But when calling by FOP2 panel (by entering number or by speed dial plugin) in FOP2 it still looks like operator calling himself.
In this case the first call is to operator's phone, second is to destination and farther asterisk bridging them. But is there a way to show destination num on the button?

What do you think aboute it?

Now the problem persists when a call is originated from FOP2 through trunk. Regardless of ignore_clid_on_bridge.
If ignore_clid_on_bridge=1, call from phone looks good even after answer.
PS. asterisk 13.
