Thank you for your detailed response. Sorry for the trouble but would
you be able to also answer the following.
Do you know if this same type of deployment would be suited to our
needs. Many of the Asterisk servers we host are for clients, who have
their own extensions, voicemail, ivr etc. I was hoping I could setup
routes on the kamailio and direct them to the appropriate asterisk
server.
Initially I thought it would be as simple as setting up an inbound
route on Asterisk. Ha.. I also installed siremis 3.2 and perhaps
reading on how to use it will provide clearer details.
I know so little, I'm not even sure if I need to have Kamailio and
Asterisk running on the same server, since I only want Kamailio as a
proxy.
Regards,
Greg

We were in similar situation. Many years with Asterisk
and then we were
forced to use ser - and we preferred Kamailio.
Now we do:
Kamailio has global IP address and clients register to it.
Kamailio forward all calls to Asterisk boxes using following:
ds_select_dst("1","4");#You can use many asterisk boxes this way
$sht(forw=>$ft)=$du; #this way I store used path
I used t_relay, instead of forward, because my Asterisks are with local IP.
Calls from Asterisk are send to Kamailio if they are to local user, or to
our SIP provider. There are no problems with calls from Asterisk to SIP
provider, even if Asterisk is behind NAT.
Asterisk accepts calls from SIP provider though registrar lines in
sip.conf. Asterisk can forward calls from our SIP provider to local users
in Kamailio.
I got problems with ACK and BYE. To solve them, I used
if(($td=="sip.name.of.kamailio.server.com")||($si=="IPofServer")){
$du=$sht(forw=>$ft);
}

Hello
After much reading I have come to the realization that after years of
using Asterisk I know very little about Sip.
I have my Kamailio box up, I have Asterisk 1.8.x running with realtime
working. I thought it would be just a case of registering SIP trunks from
my provider to the kamailio and registering our internal asterisk servers
to the kamailio.
Much of what I read talks about using Asterisk as the PSTN interface, but
that interface is through a sip trunk purchased from a provider. Won't
Kamailio be the PSTN gateway? The idea here is to pool all the sip trunks
from the various hosted asterisk solutions (VM running asterisk) and point
them all to a proxy to facilitate the aggregation of traffic.
I have been reading SIP tutorials and the mailing list archives. If
anyone has a sample config and perhaps a little direction it would be
highly appreciated.
Thank you
Greg
