I'm testing dispatcher with failover (tesitng both probing_modes: automatic
with 1, and 0 with failure_route). Opensips is dispatching calls to 2 Asterisk
servers. If I stop one of the Asterisk servers, that node becomes Pending as
expected, but when I restart the node, it doesn't turn Active again.
Here is my test:
1. I start Opensips with both Asterisk nodes Active (Asterisk is running on
both servers)
ds_list ( opensipsctl fifo ds_list) shows both nodes Active
2. I stop Asterisk in Server B
ds_list shows 2nd node as "P" pretty much right away for mode 1, and after the
1st failed request comes for mode 2
So far, everything is OK
3. I start Asterisk in server B
ds_list still shows Server B as Pending (both for mode 1 and 2); however, it
never goes back to Active unless I restart Opensips
If I start Opensips when one of the nodes Pending (Asterisk off), and later
start Asterisk on that node, ds_list still doesn't report it Active.
The log (debug=4) shows both nodes sending the <OPTION> reply, but for some
reason ds_list doesn't reflect that, and ds_select_dst ignores the new "active"
node.
Any suggestions? I'm pretty sure I'm missing something very simple.
Below is my code.
Thanks,
Matt
