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:[email protected]:5060 Br.cnt=1
Sock[0]=<null> Sock[1]=<null> [email protected]
The records in the location table both have data in the socket field. This is
running on version 2.2.4 of OpenSIPS

Subject: Re: [OpenSIPS-Users] Location table - how to use socket
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.
