That probably means they are not using SIP, but, instead are using either H.323 or some other proprietary ugliness. That's unfortunate.
You can use SIP through a NAT, if you can hack the NAT to poke particular ranges of ports back to devices on the internal network.
There's no useful way to use H.323 through a NAT though, at least that I have seen working.
SIP has to include the IP address of the RTP destination in it's payload.As such, you can't use SIP cleanly across NAT unless the NAT box knows to proxy the SIP and edit the payload (very messy).
Yeah, that's not actually the case. Joe
