[asterisk-users] Remote-Party-ID set to 0 on re-invite using pjsip in Asterisk 16.

We've been using Asterisk 16 for a while now, and tried turning on 
send_rpid = yes in my pjsip config for end points.  This solves a 
problem we're having where attended transfers aren't updating the 
CallerID when the transfer is complete (it would show the callerID of 
the party attempting the transfer, and never update after the transfer 
happened).


The side effect of this change is that now on all outgoing calls, the 
phone I placed the call on shows 0 as the dialed number, which is wrong 
of course.  This shows up in a pcap to the phone that dialed as a 
re-invite sent back to it (before the call even connects), and shows 
something like:

Remote-Party-ID: 
<sip:0 at hostname-here.com;user=phone>;party=called;privacy=off;screen=no


I'm not really certain why Asterisk is setting a Remote-Party-ID to 0, 
which I believe is the default.  Clearly it knows who it's calling.   I 
could fix this by explicitly setting the header, but that seems wrong, 
and Asterisk should be setting this correctly.

Any help is appreciated.  I've gone through a bunch of different 
attempts to fix this by changing pjsip settings (none worked), but in 
the end I don't know why Asterisk sets this header so wrong.

We're using Asterisk 16.30, and of course pjsip.
