Summary: [patch] Remote (called) Party Identification -
chan_sip & chan_skinny implementation
Description:
Overview:
This patch provides the ability to rewrite the called party information
on
channel types that support it. Implementations for the SIP (see note
http://bugs.digium.com/view.php?id=1)
and Skinny (see note http://bugs.digium.com/view.php?id=2) channels have been
provided.
Current features are:
1. Make changes whilst the call is progessing though the dial plan, ie:
exten => s,1,RemoteParty("Voicemail" <123>)
exten => s,n,Answer()
exten => s,n,VoiceMailMain()
2. When using call pickup it will rewrite the caller information showing
the caller that was picked up.
3. When unparking a call it will show the caller*id of the parked call.
The ability to rewrite the calling party identification on semi-attended
transfer is planned but doesn't work yet.
Implementation:
Transmission of the remote party data is done using indications with a
new
subtype of AST_CONTROL_REMOTEPARTY, format of the data is:
"name" <number>|presentation
Any channel specific code is kept in it's _indicate() handler. Once the
channel driver has received the indication it uses the method specific to
it; in the case of SIP it sends a 180/183 response if possible and with
Skinny it uses transmit_callinfo().
Note http://bugs.digium.com/view.php?id=1: The SIP implemenation is only able to
update the remote party
before the call has been answered as there is no re-invite support yet.
Note http://bugs.digium.com/view.php?id=2: I don't have any Skinny phones so no
testing has been done on
that part.

In that SIP trace the Polycom is replying with 501 to the UPDATE request
even though it indicates support for UPDATE in it's OPTIONS response.
I would guess that the Polycom probably wants to see a PRACK request
before and UPDATE (ie: how the RFC says UPDATE should actually be
implemented).
1.4.19-experiments.patch contains two new SIP options, setting
needprack=yes will send a PRACK message before an UPDATE. andrew: would you
be able to test this?
The other option is rpidtype=passerted which will use the
P-Asserted-Identity header instead of Remote-Party-ID. iwes: can you please
confirm if that works with you SNOM's.
