Hi,
Is it possible to have FQDN in the Via and Record-route header instead of IP address in SER?
Thanks,
Zeus Ng

This is generally a bad ideea, but if you really want to, there is a way: set advertised_address="myname.com" in your config and all your messages will have "myname.com" in their Via (this can be any string, no check will be made). If you want to do it only on a per message basis (and not for all messages), use set_advertised_address("..."). Notice however that in this case any compliant sip proxy will add a received=ip to your via, and they will use that ip when sending the replies back (and not your fqdn).
More info in sip_router/NEWS, grep after "advertised".

Hello Andrei,
What do you mean by 'is generally a bad ideea', the only point I see is the SRV problem in the FQDN. What else makes you think it is a bad idea?
Thanks a lot,
Chuck.

In my opinion hostnames should not be used in header fields which are processed by machines, like Via, Route & Record-Route, and Contact.
Resolving hostnames puts too much burden on the server, it can be ambiguous (you can get several IPs for a single hostname). Just remember that you have to send a DNS query each time you resolve a hostname, in a single message it can be Via, one or more Route headers, and Contact.
The main purpose of hostnames is to allow humans to remember (otherwise hard to remember) IP addresses. It makes no sense to me to put them in header fields which are not for humans.
