Hello Bogdan,
Here is the code I used to check $(branch(socket)[N]):
if (lookup("location")) {
set_count("$branch(uri)", "$var(brcnt)");
if ($var(brcnt) > 0) {
# More than one contact - not possible to check socket data
xlog("L_WARN", " R3 IN: Req.type=$rm R-URI=$ru
Br.cnt=$var(brcnt) Sock[0]=$(branch(socket)[0]) Sock[1]=$(branch(socket)[1])
Call-ID=$ci\n");
} else ...
And here is the log file output when I have two registrations on the same
username
R3 IN: Req.type=INVITE R-URI=sip:01NNNNNN@12.34.56.245:5060 Br.cnt=1
Sock[0]=<null> Sock[1]=<null> Call-ID=41d17a02...@sip1.mysipdomain.com
The records in the location table both have data in the socket field. This is
running on version 2.2.4 of OpenSIPS

Hi John,
the only way to share records via DB is to use DB only - the other modes are
using the DB just for restart persistence reason (they do not read from DB at
runtime, only once, at startup). In DB-only mode, all reads and writes (related
to contacts) are done against the DB.
In regards to $(branch(socket)[N]) - do you use it after a
lookup(location) ? are you sure that the N'th branch exists and have a socket ?
You may consider saving some extra attributes next to the contact ( see
http://www.opensips.org/html/docs/modules/2.2.x/registrar.html#idp5568288)
to identify the pop/host which produced that record.
