Bogdan,
This is how I have I have been using it as a workaround. This does work 100% of the time and $du is being populated by the dispatcher addresses in round-robin.
ds_select_dst("1", "4");
switch($du)
{
case "sip:192.168.1.1":
xlog("reg destination address is $du\n");
t_replicate("sip:192.168.1.1");
break;
case "sip:192.168.1.2":
xlog("reg destination address is $du\n");
t_replicate("sip:192.168.1.2");
break;
}
I changed it to the if statement you suggested and I also see the expected behavior. The correct IPs are being logged from the xlog("replicating to $du \n"); statement.
The strange part is this:
Using the following
> if ( ds_select_dst("1", "4") ) {
> xlog("replicating to $du \n");
> t_replicate("$du");
> } else {
> xlog("failure to select");
> }
The first 4 registrations processed triggered a "failure to select". After that, it started working as expected. I have since restarted the service 5 times with no occurrences of failure.
After this I reverted to the original configuration of
ds_select_dst("1", "4");
t_replicate("$du");
Dec 23 10:09:39 [16005] ERROR:core:parse_uri: bad uri, state 0 parsed: <<nul> (4) / <<null>> (6)
Dec 23 10:09:39 [16005] ERROR:tm:uri2proxy: bad_uri: <null>
Dec 23 10:09:39 [16005] ERROR:tm:t_forward_nonack: failure to add branches
I will run it in the if statement for a while and monitor the results.
Thanks,
Jody
