[SR-Users] record_route_advertised_address causes null send socket error

[Daniel Greenwald]

Yes but 2 problems with this:
1) listen parameter does not seem to accept an SRV or hostname
listen=udp:MYPRIVATEIP:EXTERNALPORT advertise EXTERNALHOSTNAME
causes the listen line to be ignored

2) My goal is not to do any state replication so I only want the SRV in
record-route not VIA. VIA will still have IP. These are very light configs
(no Dialog or backends etc) If a kamailio goes away, an in-dialog request
should still hit another kamailio and the call will progress as if nothing
happened. (Yes, in-progress Transactions will still fail but that's
acceptable vs cost of TM replication)
