I have a gateway who's voice notification profile is working and successfully calls out on the VOIP profile.
However, after taking a backup and restoring it on a different machine the call is no longer getting through. I had to re-create the profile because I was initially getting an "unknown[-1]" status.
In the logs I have this message.
java.lang.NullPointerException: Cannot invoke "net.sourceforge.peers.sip.transport.SipMessage.getSipHeaders()" because "sipMessage" is null

I have not been able to find anything on this error message.
