Apparently, you cannot disable these settings on the routers, Just spoke with Netgear, any suggestions of which routers/switches I should use that are moderately priced?

Yes, Netgear implements a weak SIP ALG that breaks interoperability with sipXecs, therefore you must disable it. I believe that Netgear refers to their SIP ALG option as SPI (stateful packet inspection) - look for this in the Netgear config pages. _______________________________________________ sipx-users mailing list [email protected] List Archive: http://list.sipfoundry.org/archive/sipx-users Unsubscribe: http://list.sipfoundry.org/mailman/listinfo/sipx-users sipXecs IP PBX -- http://www.sipfoundry.org/
