This is my first go round' with Kamailio but I have
been messing with it off and on for a few weeks.
Running latest version on latest CentOS 7.x.
Kamailio installed on VM with public IP in one location, 2
SIP phones behind same NAT, both registered to Kamailio fine.
I can call one phone to the other and it rings and I can
answer it but get one way audio most of the time, sometimes no
audio at all.
I just did a standard install with MySQL and no other
modules.
What am I missing, do I need RTPPROXY? Will Kamailio allow
extension to extension calls from/to phones behind NATS
without any additional modules?
I tried installing it with yum, it installed but it won't
start. If I need it, I will remove the YUM version and install
from source or GIT or some other method.
I do NOT want any media passing through this server, that's
one big reason I am learning something OTHER than Asterisk
which I am very familiar with.
I see all these RTP modules, music on hold etc but I
specifically don't want to install anything that causes media
to pass through the box.
Finding the learning curve much steeper than Asterisk back
in the day and a REALLY tough time find step by step examples
to get started, especially on CentOS.
I bought the draft of the book and it will be a great
resource but at the moment, it's not helping me get started or
get my first instance up and running.
I need to add SIP trunks to originate and terminate calls
but I can't even think about that since I can't even get audio
on extension to extension calls yet.
I also see that Kamailio fails to startup at boot because
it can't connect to MySQL, when I restart Kamailio it starts
fine. I think the issue is that Kamailio is trying to start
before MySQL is up and running, I guess I can do a delayed
start of Kamailio to fix that later.
Any help would be appreciate by this NEWB.
Thanks in advance for any assistance.
