[Serusers] lookup 2 uri

[Samuel Osorio Calvo]

If you know in advance the IP of 1002 and it is static, you can use serctl to add it's contact. This way doing a lookup("location") for 1003 will return both contacts...it's not a nice solution but it whould work.

Hi Samuel,

That's a very good detailed explanation! That's exactly what happened.
In my existing config, I have the logic to deal with the second ring
to 1003 at test.com. It forks to itself and creates another ser
transaction. I'd like to make it simpler by doing it in a single
transaction.

One way I am thinking about, but haven't tried yet, is when 1003
registers, ser adds its location to both 1002 and 1003. So when ser
does lookup("location") for 1002, the real location for 1003 shows up.
Not sure that it is feasible.

Thanks,
Richard

If the DNS is properly configured, test.com should point to SER itself, making SER sending the message to itself via the network. Depending on the config file, it can work but you should check the logs to see what is exactly happening.
