CISCO SPA525G2 IP Phone Continuously Reboots When Connected To Network

[alteredstate]

I recently purchased a Cisco SPA525G2 IP phone but it continuously reboots when connected to my network either via WiFi or a wired connection.  The phone will then lock up and the Mute button will illuminate solid red after about the third reboot.  I have reset the phone to factory defaults but that does not help.  The phone is also running firmware version: 7.4.8 but I cannot access the Web UI long enough to perform a firmware upgrade.  If anyone could help remedy this problem then I would be very appreciative!

Hello Marcus,

     Is the phone being powered by PoE or adapter? May want to try using a adapter if you haven't tried already. If you take the phone off of the network do you experience the same issue? Is this a brand new install/purchase? How often are the reboots or does it keep rebooting back to back?

At this point could be just a hardware issue. Not sure what else you can really do to get it to work correctly. I would try powering it up with a adatper and unplug it from your network and see if it keeps rebooting.

Hope that helps

Thanks,

Thank you for your reply Clayton but the phone is already powered by an AC adapter.  After speaking with Cisco technical support, apparently this phone's official model is: SPA525G2-RC V01 (remote customization).  This means Cisco has pre-programmed the phone off the assembly line to only work with a specific PBX provider and the end user can not make any changes.  Basically, I just purchased five brand new $200+ paper weights!

Hello Marcus, this information is correct. The correct course of action is to return the phone to the reseller. If you purchased the phone from a service provider, they will need to support the telephone. Any of the Cisco small business products with RC, R1, R2, R3, R4 and TLS are devices that have been programmed in to a datacenter to pull configuration specific to a service provider.

If there are any issues with returning the phone to the point of sale, you may try asking for a RMA if you're able to supply a valid proof of purchase. But the first and foremost process would be to return to the PoS.

Hello Marcus,

Yea that makes since now. So sounds like its constanting trying to be provisioned so it keeps rebooting. All that Tom says is correct though. If you can not go back to your PoS it surly wouldn't hurt to call Cisco Support back and ask if they can provide you some type of exchange if you are out of your return period.

I hope they are able to help you out though!

Thanks,

Thank you Mr. Sill and Mr. Watts.  I returned the SPA525G2-RC phones and purchased the correct model.  I just set one up and today and it works great!  Thanks again for the assistance!
