Hi,
I’m very appreciated if someone can figure out this problem for me.
My aim is to setup HA Kamailio using Dispatcher module in Amazon EC2, system like this:
soft phone 1(Linphone) —————> | Load balancer —————> | Sip Server
huancomputer | private IP: 172.31.11.35 | 172.31.13.113
soft phone 2(Linphone) —————> | public IP: 35.166.179.244 | 35.166.152.104
huannguyen | |
The dispatcher.lst config file in /usr/local/etc/kamailio as below:
# gatewayss
1 sip:172.31.13.113:5060;transport=udp <sip:172.31.13.113:5060;transport=udp> 0 0 abc=xyz
User records subscriber table:
———————————————————————————————————————————————————
id | username | domain
———————————————————————————————————————————————————
70 | nguyenhuan | nguyenhuan at ec2-35-166-179-244.us-west-2.compute.amazonaws.com <mailto:nguyenhuan at ec2-35-166-179-244.us-west-2.compute.amazonaws.com>
71 | huancomputer | huancomputer at ec2-35-166-179-244.us-west-2.compute.amazonaws.com <mailto:nguyenhuan at ec2-35-166-179-244.us-west-2.compute.amazonaws.com>
Location records from location table:
———————————————————————————————————————————————————
username | domain | contact
———————————————————————————————————————————————————
huancomputer | NULL | sip: huancomputer at 14.161.41.70 <mailto:huancomputer at 14.161.41.70>:64166;transport=udp
nguyenhuan | NULL | sip: nguyenhuan at 14.161.41.70 <mailto:huancomputer at 14.161.41.70>:33267;transport=udp
But soft phone 1 cannot make a call to soft phone 2, below is data is extracted from wireshark:
