[OpenSIPS-Users] dns srv lookups happening during relay

[Tito Cumpen]

I enabled debug level 6 and I am noticing this
: DBG:core:mk_proxy: doing DNS lookup...
Aug 14 20:42:09 cloud-server-06 /sbin/opensips[22814]:
DBG:core:sip_resolvehost: no port, no proto -> do NAPTR lookup!

Here it claims that this request is lacking a port and and a proto on this
branch I am appending the branch like so


  avp_pushto("$du","sip:sisterproxyIP");



                                        append_branch();


the sister proxy is where the user resides. This is actually confusing the
remote opensips  proxy(same version) because now it sends all in dialog
request via a tcp socket all thought the 200 was sent via udp leg. 2
requests came into the sister proxy. I'm not sure why the one gets a 404
and the proceeds the only difference is the udp request has two rr headers.
It appears that the remote proxy might not have cancelled the dialog even
thought it sent a negative reply. I have a trace of this if needs to be
supplied.


Thanks,

Tito
