[OpenSIPS-Users] Serialforking failure, with lcr:parse_phostport: too many colons in udp:: 0

[Bogdan-Andrei Iancu]

Hi Taisto,

These new functions do replicate the behaviour of the old lcr 
functions..the idea was to make this serialize mechanism globally 
available for all modules.

Now, if all contacts have the same Q, there is nothing to 
serialize.....Probably it will be more logical to return "false" to 
script in such a case (if no serialization was done)....But you can do 
something like:

--------------------------
lookup("location", "m");
switch ($retcode)
{
case 1:
    log(2, "(lab2) - Contact found in location server, rerouting.\n");
    if ( serialize_branches(0) && next_branches())
    {
      log(1, "(lab2) - serial forking in progress\n");
      setflag(NN);  # remember to resume serial forking in failure route
    }
    xlog("sending to RURI=$ru ; branches=$(branch(uri)[*])\n");
    return(1);
---------------------------


Regarding the timer stuff, see my prev email.

Regards,
Bogdan
