I'm getting an intermittent outbound issue and it appears to
be a problem between the proxy and the bridge during an
invite. Below is an excerpt from the trace. The first invite
was from a successful call, the second from a failed call.
Both were to the same number within a minute of each other.

Version: sipXecs(4.4.0)

Successful call:
