Fixing the multiple phones behind NAT problem
*Working perfectly some of the time, and not others
*Stopping working one day with no apparent reason
*Working when there is only one phone behind NAT but not when more than one. This is caused by muliple phones using the same local SIP port, and/or the same local RTP port. Each phone should use a different local SIP port, and a different local RTP port or non-overlapping local RTP port ranges.
