I am setting up a private asterisk system for a non-profit that doesn't have much money so I'm looking for inexpensive phones.   I see that there's a lot of older model Polycom, Cisco and other phones stickered or marked as former RingCentral phones on Ebay that are inexpensive.  I've read that RingCentral used to give out the admin password to phones when the accounts were closed, is this still true?  From what I've read the Ringcentral Polycom phones are fairly easy to reset passwords on while the Ringcentral Cisco phones are very difficult but if I can contact RingCentral and give them a serial number for a Cisco phone for example it would be much easier than trying the various cracks I've read about on the Internet.  Or am I just asking for trouble and will end up with a bunch of bricks if I try going this route?

Also, what is the absolute dirt-cheapest way to get a couple SIP trunks for an asterisk system from Ringcentral?  No voicemail no call waiting no cloud PBX junk, no nuttin - just caller id, rollover busy, and busy signals if both trunks are active.  The site seems geared to selling lines for individual phones.

Once you do a factory reset of the phone, you're back to square one and can do whatever you want with the phones.  The password would go back to default password.  I've done both (Cisco & Polycom) w/o issues.

The Cisco docs on phones like the SPA303 make it crystal clear that the phones can be configured to DISABLE the factory reset - until you enter in the admin password.  Hence my question.  Does RingCentral do this?  From what I have read, yes they do.  Will they give out the password needed to login and factory reset the phone?  From what I have read - at one time they would.  Do they still do it now?  Heck if I know.  Do you know?  Or are you just relying on dim memories of a phone you might have reset 4 years ago?
And by the  way, I _have_ done RingCentral Polycom Soundpont 335's before.  And YES they DO disable the factory reset key sequence.  You have to setup a provisioning server and break out of the phones boot sequence.  But the Cisco has no breakout during the boot sequence.  And setting up a provisioning server isn't trivial  (it is easy just not trivial).

(I'll explain it this way)  Two weeks ago, I had a client who was a RC customer and had phones bought through RC.  They moved to Vonage and all I did was reset back to factory, then reprogrammed them to the Vonage network.  Been working fine since then.  I have never had an issue with resetting back to factory w/RC - estimating I've probably done it a little more than 100 times over the past 6 years.

If I to guess, the only phones that it would make sense for RC to disable factory reset would be rental phones.  And if someone is selling those phones - then that's a problem!

OK that makes sense.  Although I suspect that if someone with an old phone (like for example a Polycom SP335) that was a rental decided to cancel, that RC will have made quadruple the cost of the phone on the rental fees of the unit over the years, and if the person disappears and never returns the phones, since they aren't in the current rental lineup, I would imagine RC would just write them off.

I used to run a DSL ISP and quite often we would get customers who demanded a free DSL modem on signup, our response was to "rent" them one for a few bucks a month.  We would buy them used and send them out the door.  About half the time when they canceled we would never get them back.  Sometimes if the customer had been a particular support pill I would go over to their house after hours and knock on the door asking for the modem back.  About half the time I got them the rest of the time I got the usual "we threw it away" or "I can't find it" baloney.

Like most things on Ebay this probably falls into the "try it and find out" category...

Hi Ted,

RingCentral will lock phones with a unique password if they are under warranty, or if they are rental phones. After that, if requested, we can unlock them so they are using the default password provided by the manufacturer.

If you purchase a phone that was previously on a RingCentral account, and if the phone has not re-provisioned with our service since the phone was unlocked or since the account had been removed, then it may still have the unique password. Polycom phones do have a way to reset the phone back to the factory default settings without the admin password. However, Cisco phones, from my experience, often will only be able to reset to factory by using the current admin password or by setting up a TFTP server on the local network.

If you get a phone that you believe has a unique password set by RingCentral, support can provide the password if the phone is not associated with a current RingCentral account, and if you can verify that you are an admin on the account you wish to add it to.

Sorry for my english.

I am not a RC customer. I bought on ebay an old deskphone Linksys SPA922. After I turned it on, it became clear that it was locked to RingCentral. To reset to factory settings, an administrator password is required. The seller did not help me and refused to do a refund :-( Phone serial number is 4MK00HC20534. I really hope for your help. I ask you to help me get an administrator password or make a complete reset.

Thank you!

Thanks everyone, I solved the problem. Googled articles, configured Wireshark, Apache2, mod_rewrite, intercepted a request from the phone and slipped to it another config. Full reset is complete.
