>From the issue, it was determined that using pj_gethostname() to populate the origin line of SDPs is not guaranteed to meet RFC 4566's requirement that the address be a FQDN or IP address. This changeset modifies the process by getting the hostname and then resolving that into an IP address. On my box, I could change the IP address by modifying my /etc/hosts file to resolve my hostname to a different IP address.

Placed an outbound call from Asterisk. I observed that the SDP origin line now contained an IP address instead of a hostname. When I modified /etc/hosts to resolve the hostname to a different IP address, that IP address appeared in the SDP origin line instead.
