Sounds like NAT problems, do you have qualify enabled for these devices? Also the Linksys devices have a keep alive option (NAT Keep Alive Enable). But even with both these setting enabled NAT gateways sometimes seem to lose track of SIP sessions (I have more trouble with Cisco devices than Linux routers), setting the UDP session timeout to 10m seems to help (default is something like 3m). -- Daniel Tryba -- _____________________________________________________________________ -- Bandwidth and Colocation Provided by http://www.api-digital.com -- New to Asterisk?
