Dialling an IP5000 Phones Disconnects on Answer from external Calls



We are seeing an issue where our IP5000 phones are disconnecting external calls when we try to answer.  This appears to be only in one of our 5 offices.


We get a Sip 200 Response code with a Diagnostics ID of 10006.


I have tested phones in other locations and these work fine - if I log the account into Lync on my desktop client it answers fine - all outbound calls go out fine.


We are using UC Softwware Version

BootROM software :-


The office where the calls do not answer we have tested with a VVX500 phone and these do answer - so it appears to be an issue just in the one office on IP5000 phones.


Any advise or pointers would be greatly appreciated.

Hello Paul,

welcome back to the Polycom Community.

Did you ever solve this issue => here <= or even => here <= ?


It is extremely important that you provide feedback on older posts or these clog up the communmity with no real answer for others to find.


In regards of your new issue it could be something described => here <= but without more details it is hard to tell.


The correct escalation step would be to work with your Polycom reseller so they can open a ticket with Polycom support if required.

Best Regards

Steffen Baier
