Hi, in devel version (kamailio flavour) I try to print some selects to the log (using xlog):
xlog("L_INFO", "request transport = $sel(@v.transport), branch = $sel(@v.branch)\n");
@v.transport is indeed printed (tcp/udp...) but @v.branch is not, neither other selects as @v, @v.host and so.
Do I miss something?
So what get's printed when you use @v.branch? Nothing or some garbage? Could you also check the log to see if there are any error messages (via parsing perhaps) when you try to use one of the selects that don't work?

The request is correct (no parsing errors at all):
DEBUG: <core> [parser/parse_via.c:1287]: Found param type 232, <branch> = <z9hG4bKaxdawfnv>; state=16
Then when running this xlog:
xlog("L_INFO", "[$sel(@v.branch)] $rm from $fu ($fU) to $ru ($sel(@v.transport) $si : $sp)");
I get <null> for $sel(@v.branch):
DEBUG: <core> [select_core.c:378]: missing VIA[6] header DEBUG: <core> [parser/parse_to.c:174]: DEBUG: add_param: tag=wohrg DEBUG: <core> [parser/parse_to.c:803]: end of header reached, state=29 DEBUG: <core> [select.c:424]: Calling SELECT 0x7f5e99bd9890 INFO: <script>: [<null>] ACK from sip:test_ibc@aliax.net (test_ibc) to sip:kaka@aliax.net (UDP 192.168.1.16 : 15060)
So, what does it mean "[select_core.c:378]: missing VIA[6] header" ? It's not missing at all. It's an INVITE from Twinkle, 100% correct:

Also note that $sel(@v.transport) is correctly printed.

Interesting: If I write:
xlog("L_INFO", "[$sel(@v[1].branch)] $rm from $fu ($fU) to $ru ($sel(@v[1].transport) $si : $sp)");
Then it works (no warning about missing Via[6] header).
So:
- $sel(@v.transport works ok (retrieves transport of first Via). - $sel(@v[1].transport works ok (same). - $sel(@v.branch does not work (it says "[select_core.c:378]: missing Via[6] header"). - $sel(@v[1].branch works ok (retrieves branch of first Via).
It's clearly a bug, am I wrong?
