Hi, just as curiosity I comment that there is an error (an Asterisk error in
fact) in the material of the Rome VON course of 2007:
In file "config/08-asterisk.conf" it appears:
CREATE VIEW sipusers AS
SELECT username as name,
[...]
domain as defaultip,
domain as ipaddr,
[...]
FROM openser.subscriber;
There is a bug in case of SIP SRV domains because Asterisk doesn't perform a
SRV DNS query for the location of registerd users (just for outbound calls
if "srvlookup=yes") so if OpenSer has a SRV SIP domain
"my_srv_domain.com"
but DNS type A of that domain points to a different IP then Asterisk will
fail (it will resolve to the A DNS entry).
A simple solution is to modify the view as follows:
CREATE VIEW sipusers AS
SELECT username as name,
[...]
__OpenSer_IP__ as defaultip,
__OpenSer_IP__ as ipaddr,
[...]
FROM openser.subscriber;
Of course this is a bug in Asterisk since it should, according to RFC3261,
perform a SRV query for the location of registered users in case they are not
an IP.
Just it ;)
Regards.
