<body>nat is equal to yes,<BR>
and server definition in ftp provisioning server is correct.<BR>
i followed packets between phone and asterisk,<BR>
it seems for some reason asterisk is not happy about challenge response its getting from polycom.<BR>
why its not happening in the same LAN, beats me!<BR>
and also NAT device is cisco SIP aware and works flawlessly with Linksys.<BR>
the only close definition of issue i have found is in wiki as i mentioned.<BR>
for reminder here it is:<BR>
"If the phones fail to register with Asterisk but can still make outbound calls, you likely need to adjust the digest realm parameter from the default of PolycomSPIP."<BR>
i'll try to use SIP image for polycom and let you guys know.<BR>
<confused!><BR>
