We have several Polycom IP 650s, and about 8 of those phones have the "Switch Hook Syndrome" issue described elsewhere in this forum.   (You pick up the handset and there's no dial tone.   Or if the phone is ringing, you pick up the handset to answer the call but the phone keeps ringing, and does not answer the call.)

 

When the problem happens we can eventually get it back to normal by restarting the phone several times.  But sometimes it takes 6 or 7 restarts before it finally starts working again, which is time-consuming.

 

I gather from this thread and this thread that we should post the serial number and revision.  Here are two of the phones that display the symptom:

 

0004F267CB1B, Rev AE

0004F26988B5, Rev AE

 

All of the phones are on the 4.0.10 Rev D software.

 

Please advise how this can be resolved?  Thanks very much for your help!

Hello LarryMcP,

welcome back to the Polycom Community.

The SSIP650 in question does not have the same parts as the CX post's you described and I am not aware of any issues with these phones.

 

Both phones have been sold back in 2014 so they are out of warranty. They where sold by SCANSOURCE COMMUNICATIONS so you would need to contact them for a RMA

Please ensure to provide some feedback if this reply has helped you so other users can profit from your experience.

Ok-   thanks for the quick response, especially on a weekend.   I've got a theory that this is a software bug, since the problem happens on several of the phones.  Maybe a bug that occurs only with our specific config settings (we saw that situation once before as well).

 

What I'll do is buy a new phone and see if the problem happens with a brand new one.  If it does, I'll pursue it through the reseller and escalate through that channel.   (And if not-  guess we'll order a bunch of new phones!)
