sipXecs 4.0 contains a comprehensive near-end and far-end NAT
compensation system, which is integrated into the sipXproxy process.  It
also contains sipXbridge, which is intended for connecting to "SIP
trunking" services.  Both of them use sipXrelay for relaying media.

Since sipXecs is a proxy-based system, it handles all SIP requests
similarly.  Hence, its NAT traversal system works for SUBSCRIBEs/NOTIFYs
just as it works for INVITEs/BYEs.
