Hello,

after updating FS to trunk a few days ago I found that callee's display
is updated serveral times to caller's name after callee picked up. The
first two equal INFO messages looks like this:

INFO sip:2850 at 85.16.245.213:1040;line=367hfn9i SIP/2.0

To: "unknown" 2850


The third one is this:

INFO sip:2850 at 85.16.245.213:1040;line=367hfn9i SIP/2.0

What calle sees is this:
1. Phone rings: caller's displayname
2. Callee picks up: switching from dislayname to unknown
3. Switching from unknown to displayname

After callee has picked up caller's display is also updated with
callee's name (this is a copy of callee's number rather than callee's
name) and number.

First Question:
Can this behaviour be disabled? Or can it be modified by dialplan, so
that there is no "unknown"?




Unfortunately when you do an outgoing call via openzap and callee picks
up the phone caller's display is updated with two equal INFO message
like this:

Second Question:
Can I change the name and number via dialplan, so that the correkt name
and number is viewed to caller?
