Hi, Andreas and Alberto, I am also working on Netgear FVX538v2 with SIPX now and I'd like to share with you what I found during the test. Last weekend I updated its firmware to latest 3.0.5-27 which supports SIP/ALG now ( under "Security" -> "Firewall" -> "Advanced" ). My remote worker sip phone in internet can well register to SIPX and can dial&listen the announcement of auto-attendant. Whereas, when I dialed another sip phone within same intranet of SIPX or another remote worker in internet, after hearing the first ring back tone, there is no audio from called party. I have no idea if my configuration of remote work in SIPX or the firewall settings in FVX538 are well figured out, or if we need sipxbridge in this scenario. Can we swap these info to each other ? Regards Jun

It's a newer model than FVX538v2. Firmwares are slightly older than yours. Last public version is 3.0.3-18. I know there are some new in beta. There is no SIP ALG support in this firmware yet. It does have a single ethernet WAN and I'm using a Netgear DM111p as ADSL2+ broadband modem. I have available for testing FVS338, FVS336G and DGFV338, but did not have experiences with sipxecs with them. With sipXecs I'm currently using quite a lot sipxbridge to register few accounts with my ITSP. I'm not using the remote worker function. I did not test it at all. I'm having just one major issue with SRXN3205: it seems to behave erratically with udp traffic after a broadband failure. I have a quite noisy line that became quite sensitive the day I upgraded my ISP from ADSL to ADSL2+. It's not too bad actually but occasionally the modem drop the line obtaining a new IP. While this is not interesting if you're not is such situation I found that SRXN3205 is not correctly sending udp traffic after the line is up again. I could reproduce this issue multiple times just switching of my broadband modem. This happen only with sipxbridge in my case. It keeps an open udp channel from the time it started for performance reasons. The router does something illegal after the line is again fully operational: it send the udp packet on the Internet with source address my LAN 192.168.x.x sipxbridge IP instead of the public IP received from the ISP. Basically it stops doing its NAT function for UDP channels established before a broadband line drop. Packet with such source address are for sure dropped from the first router out there and sipxbridge will not receive responses to its requests. Don't really know if it is a specific SRXN3205 issue or it could be generalized to all Netgear Prosafe with at least the same firmware revision. I could spot the issue doing packet captures on the router on the WAN side.

If so, I'd like to swap configuration examples and lessons learned.

Dear Mr. Joly, We are currently using a NETGEAR ProSafe VPN Firewall model FVX538v2. Last month NETGEAR came out with updated firmware (3.0.5-24) which claims to have added SIP Application Layer Gateway support. Have you by any chance heard any PRO's or CON's or otherwise with regard to the FVX538v2 and any interoperability problems with sipXecs? http://kb.netgear.com/app/answers/detail/a_id/8100 Thanks in advance, Andreas Systems Engineer Around the Clock Information Systems -----Original Message----- From: sipx-users-boun...@list.sipfoundry.org [mailto:sipx-users-boun...@list.sipfoundry.org] On Behalf Of Robert Joly Sent: Tuesday, June 23, 2009 9:12 AM To: an...@iguanait.com; Scott Lawrence Cc: sipx-users@list.sipfoundry.org Subject: Re: [sipx-users] [Bulk] Re: Remote worker registration problem Thank you, Scott! I informed this user to check this router settings and he has found out some settings for sip on his router. After disabling these sip settings everything is ok and he is able to register :) May I ask what kind of router you are using? I'm compiling a list of routers that have SIP settings that interfere with sipX. Thank you. 8< _______________________________________________ _______________________________________________ sipx-users mailing list sipx-users@list.sipfoundry.org 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/
