Channelcontext in CID

[Bytegetter]

What is the reason for this line? I found some information about this, but no solution.

IF dialplan behaviour (macro-user-callerid)

Site-to-site via IAX - wrong CallerID

Configuration: FreePBX 15.0.16.42 connected via IAX2 to FreePBX 15.0.17.55 Calls from FreePBX 15.0.17.55 to FreePBX 15.0.16.42 come with correct CID Calls from FreePBX 15.0.16.42 to FreePBX 15.0.17.55 come with wrong CID: Instead of extension number we get something like: 1024-1011:123, where 123 - extension number, 1024 - always constant, next 4 digits are varying every call Looks like it was happened after update of Freepbx to version 15.0.17.55. Where to go?

Is this a bug or a scary feature?
