SPA504G crashing/blocking other networked VOIP Phones

Hi All,


I was wondering if anyone could shed some light on this problem.

I have 80+ SPA942 phones running on a 3CX v10.0  SoftPBX system and have had no problems so far.


I was tasked with supplying some new phone but keeping withing the Linksys/ Cisco family so I decided to buy newer versions of the SPA phones. I bought a couple of the SPA504G's (7.4.8a firmware)


The problem is when I plug the SPA504G into the POE port all my other phones suddenly become unregistered and the only solution is to unplug the SPA504G then walk around unplugging the phones for at least 30 seconds then plugging them back in so they re-register.


(If I don't unplug them for at least 30 seconds or if you attempt to resolve the problem with a soft reboot then all that happens is the phones keep rebooting every 30 seconds or so which is annoying to the users)


Has anyone seen this problem if so what was the fix if any ?

Wrong forum, try "small business - phones".
