Re: [reSIProcate-users] Using hostname in RR/Via causing send to fail

Hi Adam

When I start up the proxy   it prints out:

INFO | 20090302-230201.199 |  | RESIP:DNS | 1077209024 | 
dns/AresDns.cxx:141 | DNS initialization: found  1 name servers
INFO | 20090302-230201.199 |  | RESIP:DNS | 1077209024 | 
dns/AresDns.cxx:144 |  name server: 192.168.254.200
INFO | 20090302-230201.200 |  | RESIP:TRANSPORT | 1077209024 | 
UdpTransport.cxx:42 | Creating UDP transport host=192.168.254.202 
port=5060 ipv4=1


.202 is the proxy IP.  The round-robin host name resolves to both .202 & 
.201. The DNS server found is correct.


I have a C++ std::string containing the servers hostname which I use to 
build a record route & Via. If I initialise it to "192.168.254.202"  
everything works but if I initialise it to "sip.xswitch.local" I get the 
aforementioned error.

sip.xswitch.local is setup on the DNS-- if I do host sip.xswitch.local 
at the Linux shell i get:

sip.xswitch.local has address 192.168.254.202
sip.xswitch.local has address 192.168.254.201

I've just double checked - the proxy program is given two commandline 
arguments- the IP address (192.168.254.202) which resip binds to at 
startup & the round robin hostname which is used ONLY to generate Via & 
Record-Route headers. If i pass them both as IP's it works, but an IP 
and a hostname fails :S
