[asterisk-users] Opensips+asterisk problem

Tue Jun 30 06:33:54 CDT 2009

Hi Ram,

Does your OpenSIPS get any SIP reply from Asterisk? or the INVITE is 
simply discarded by Asterisk?

Regards,
Bogdan

Hi all

After a long iam back to forum
back to my own topic and several readings done on this forum
how people doing same kind of setup what iam trying to achive

so here i have done some good developements

for testing iam doing all in one Server

Step1 :

Installed in Fresh BOX with Debian

Asterisk and A2B working Fine

Step2 : registered with SIP account iam able to make calls successfully

Step3 :

installed Opensips

Made Subscribers to view from A2b Database

Step4 : changed Asterisk port from 5060 to 5062

Step5 : Opensip config made changes to register users with Opensips
and when they dial 001X call send to Asterisk box

route[3]{

if (uri =~ "sip:001[0-9]@*"){
log(1, "Forwarding to Asterisk \n");
rewritehostport("A2b-asterisk-IP:5062");
route(1);
exit;
}

Works Fine, No problems as of now

But to go in advance, i want to use Number of * boxes to achive more Load

Step5 : added Dispatcher Module in the Opensips

loadmodule "dispatcher.so"
.
.
.
modparam("dispatcher","list_file","/usr/local/etc/opensips/dispatcher.cfg")
.
.
.
.
changed route to use dispatcher

route[3]{

if (uri =~ "sip:001[0-9]@*"){
log(1, "Forwarding to Asterisk \n");
ds_select_dst("2","4");
forward();
route(1);
exit;
}

My dispatcher Config Looks like below

dispatcher.cfg
2 sip:a2b-asterisk-ip:5062
2 sip:a2b-asterisk-ip2:5062

I have restarted Opensips

when i dial 0017XXXXXX number the call send Opensips to Asterisk
