Hi,
I haven't tried it mysefl (will probably do it in a near future) but
there is core configuration parameter to be enabled.
http://www.kamailio.org/wiki/cookbooks/4.2.x/core#dns_srv_lb
As we speak, some of our clients reported similar issue when connection
to us using FreeSWITCH and setting weight to 0 seem to resovle the issue
(it was prosposed solution on freeswitch mailing list)
We internally don't do SRV LB in outbound direction but probably will so
please come back with your results.
I had the issue in the past and here's how it was solved:
- When sending your "first" request to the server resolving it by DNS, you can
store the destination IP in a hash table (callid--> IP) using onsend_route
The kamailio script should check something like this:
1: Initial request. Is the callid in hash table?
Yes --> Don't resolve DNS and send it to the stored IP
NO --> Use DNS to send it and store the IP using onsend_route
If you set the autoexpire of keys to 3-4 secs it will work well.
cheers,
Jon
