Outgoing call recording doesn't work on zap extensions

When you configure a zap extension with:

{noformat}
Record Incoming = Always
Record Outgoing = Always{noformat}

It records incomings calls to that extensions without issue.

But it won't record the outgoing calls of that extensions. At Asterisk console the error says it could not find the AMPUSER for that extension and hence "No recording is needed".

The only way I could solve this was by setting the "callerid" variable inside zapata.conf, like this:

{noformat}
context=from-internal
group=1
signalling = fxo_ks
callerid="John" <502>
channel => 6{noformat}
