[Asterisk-Users] SRV lookups

[Robert Spielmann]

Hi everyone,

I have a question concerning DNS SRV lookups. The situation is like this:

- one central Asterisk server
- many domains with SRV records, let's say we have bar.com and doe.com

Now the question is: if the SRV lookup is done for foo at bar.com the call is 
mapped to foo at myasterisk.mydomain.net. Is that correct?

If so, I have a problem: if somebody calls foo at bar.com, Asterisk receives only 
the "foo" part. If someone calls john at doe.com, it receives "john" as the 
extension. Now the main question is: how do I know which SIP address the call 
originally went to?

If I lose the domain name prone to SRV lookup, I can't decide where to route 
the call - for example, there may be john at doe.com and john at bar.com, both get 
mapped to my central Asterisk server - I'm unable to know which of the john.s 
is being called, hence I cannot route the call correctly.

Hope the question is clear enough ;)

TIA,
Robert
