[asterisk-users] Phone losing IP address for a few seconds but doesn't drop call
Hi, Recently I've noticed on a customer's GXP-2000 phone that it loses its IP addresse for a few seconds, audio goes blank obviously, and after about 30-60 seconds get the same IP addresse back and resumes the call. This shows that call was not dropped but phone lost connection with the server, whereas the caller on the other end was still talking. This is just unacceptable as this is effecting his business. Apparently this is a router related issue. Its a D-Link DI-624 router. This happens even when there is no Internet activity at all. How can this issue be resolved. What are the reasons for losing contact with the router. Is there some interference at port 5060, bad wiring, or something else? -- Zeeshan A Zakaria ___ --Bandwidth and Colocation provided by Easynews.com -- asterisk-users mailing list To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users
Re: [asterisk-users] Phone losing IP address for a few seconds but doesn't drop call
Does it loose it's IP address consistently and at a designated interval. I've seen something similar in a number of various cases where it was always an issue of the 'client' device blocking the DHCP renew traffic. But when it went into rebinding it would drop $filter and allow the dhcp traffic back through. I would say check to see if it occurs at a regular interval and compare that with the lease times. Also consider it's sometimes a good idea if the phone supports it (I don't know if your does) but setting up a cheap syslog host that can catch the syslog messages from the unit. Some units will log why they dropped their network (ie dhcp) or something. This was just a wild stab.

This shows that call was not dropped but phone lost connection with the server, whereas the caller on the other end was still talking. This is just unacceptable as this is effecting his business. We have also had this happen at client sites. I don't think it's a router issue, since we've had the same thing occur using a variety of different routers. There are 2 possible reasons for it: 1) The firmware version on the GXP2000 isn't doing DHCP queries properly - when it connects to the server to renew its IP, instead it thinks the server's given it a different one (which of course it hasn't). I'm guessing the phone drops the network interface then brings it back up. 2) The auto check firmware every option was known to cause the phone to reboot in some firmware versions when the phone checked for new firmware/config from the TFTP server. We worked around the issue at one place by giving all the phones static IPs (and configuring them in the phones manually) and disabling auto check firmware. At another location where static IPs would have been impractical (some staff take them home at weekends), we simply upped the lease time on the DHCP server to 7 days. Of course, you may find that simply trying different versions of the firmware resolve those issues. Regards, Chris -- C.M. Bagnall, Director, Minotaur I.T.

As others have said, it does sound like a DHCP issue.. you can try increasing the lease time, or giving it a static IP address.

Sounds like DHCP to me. I've not had this problem with a GXP-2000. If it were me, I would try setting the IP address to a static IP to rule out any kind of DHCP weirdness. Now, if it still happens, then it's not really losing its IP; instead, it will be losing the connection. Or it could be unregistering with the Asterisk server for some reason, and then re-register 30-60 seconds later. That's still bad, but it's different than losing one's IP. One way you may be able to more accurately diagnose the problem would be to run Ethereal or some other packet sniffer and see if the voice packets get through your router. If not, fix or replace your router. If so, you'll need to do more detective work to see if you have a phone problem, configuration problem, cabling problem, bad port on the switch, etc. Hope that helps, David ___ --Bandwidth and Colocation provided by Easynews.com -- asterisk-users mailing list To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users
Re: [asterisk-users] Phone losing IP address for a few seconds but doesn't drop call
Thanks for all the replies. I've updated client's router firmware, which was very old. Now I've put MoH on for the whole day and see if it happens again. MoH was doing the same thing, i.e. going down and coming back up. When it went down, on the screen you could see message saying 'No IP', and when it came back up, same old IP was back. Phone's firmware is the latest one, which is on their website, i.e. 1.1.1.14. I know there exists some latest but still beta version of a firmware, but I'll stick with this one. There is no pattern when it goes down, it may does it twice an hour or not do it for many hours. But I've noticed that Automatic Upgrade Option was set to 60 min, I've now set it for 1440 minutes. Does automatic upgrade means only firmware upgrade or config upgrade as well. Can I have config upgrade sooner than 1440 minutes on this phone? ___ --Bandwidth and Colocation provided by Easynews.com -- asterisk-users mailing list To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users
Re: [asterisk-users] Phone losing IP address for a few seconds but doesn't drop call
Physical connection is fine because customer's computer is also connected through the phone's inline ethernet port. When phone was losing IP, computer was still working fine on the Internet. But after the changes I made earlier today, as mentioned previously, it seems to be working fine so far. I'll check it again from them at the end of the day. ___ --Bandwidth and Colocation provided by Easynews.com -- asterisk-users mailing list To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users
Re: [asterisk-users] Phone losing IP address for a few seconds but doesn't drop call
Hi, Sounds like a flaky physical connection to me. Try new patch cables (DO NOT EVER use homemade patch cables, they cost too much) and a different jack if in an office environment. If that doesn't fix it, try locking the switch port and/or the phone port speed/duplex settings and turn off auto-negotiation. Try a different make/model of switch (insert between phone and router). regards, Drew Zeeshan Zakaria wrote: Thanks for all the replies. I've updated client's router firmware, which was very old.
