Hello,
I'm testing DMQ_USRLOC modulo between two Kamailio servers (A) and (B)
The two servers share the same domain and using Amazon Route53 to distributes 50%
requests each Server.
The problem is when I try to make a call from user A (registered on kamailio A) and the
user B (registered on Kamailio B).
The call follow this flow:
User A --> KamailioA --> UserB
go directly to userB because KamailioA know, via DMQ_USRLOC IP and port of UserB. With
some Softphone the call work with audio without problem; with other Softphone USERB never
answer the INVITE sends from Kamailio. Is it possible use this flow?
USER A --> KamailioA --> KamailioB --> User B
to resolve this kind of problem or is there other available option?
If the softphone is behind NAT it has a relation to one IP address in the NAT. You need to
send the INVITE from that IP and no other IP in order to reach the device. Even without
NAT, many devices just don’t respond to messages from unknown IP addresses.
