[SR-Users] Kamilio and AWS Route 53 latency regions

[Coy Cardwell]

Thanks.
I am using DB only mode.
There will be a number of servers in the end, so i will have to look
further into the issue I guess, since assumptions were made about how
Kamailio works.

and a central registrar.

Thanks again for the replies.
