[asterisk-users] Grandstream GXP2000 Loses Connectivity
I have 20-30 GXP2000's connected to * over a T1 line. Neither end is NAT'd and there is plenty of bandwidth available over the line. The GXP's are 1.1.5.15, which is the latest. I have a problem where the phones keep dropping off of * and I get a "failed to register" message in the log of *. Sometimes they eventually connect and sometimes, I have to reboot them to get them to reconnect (I never change the config though). Has anybody seen this? I've tried lowering the Register Expiration and that seems to make it worse. If I lower it to 1 minute or 5 minutes, I lose them every 10-15 minutes. If I put it at 10 minutes, it loses connectivity once or twice a day. I tried Grandstream support and their answer was completely useless. Has anybody seen this? Or does anybody have any ideas? Again, no NAT involved, so don't say STUN or NAT issue. Peder

Yes but network issues are still possible. What sort of network connections are you using? What sort of routers/firewalls/other network gear? Are you certain of the reliability of the T1? Also you did not post what Asterisk version is in use. Please also post the relevant sip.conf and configuration file of the phone.

Can you test this whole thing with a phone? On Feb 11, 2008 4:52 PM, Peder @ NetworkOblivion <peder at networkoblivion.com> wrote:> I have 20-30 GXP2000's connected to * over a T1 line.
