Follow up to the group: the domain he is trying to reach only has SRV records for TLS and TCP, so he has to append ;transport=tcp to his request URI to force a TCP SRV lookup in opensips.

OpenSIPS follows RFC3263, see sip_resolvehost() in resolve.c for more details. If you send a a request that is not a sips uri, to a plain domain with no transport parameter or port, opensips will do a udp SRV lookup on the domain.

Can you provide the actual domain please? If you cant - do a srv lookup on it to verify it actually has an SRV.

dig _sip._udp.blabla.webex.com SRV

OpenSIPS does not appear to be resolving the SIP address of a domain that is provided by WebEx.com. When I dial dlar...@blahblah.webex.com <mailto:dlar...@blahblah.webex.com> the call gets forwarded to the IP address of the webserver but it really should be going to the IP address from an SRV record. I believe the OpenSIPS default is to resolve DNS and also SRV records correct? I wasn't sure if the issue might be because the domain is BlahBlah.webex.com <http://BlahBlah.webex.com> but I don't have any compare since all the test domains I call (200...@login.zipdx.com <mailto:200...@login.zipdx.com>, telephr...@voip.telephreak.org <mailto:telephr...@voip.telephreak.org>) have the same IP for the web as it does for the sip.
