Hello Damir,

Unfortunately, the SPA900 series phones are not supported with the UC500 platform.

You can find information regarding supported phones at the following links:

John,

Thank you very much for your answer.

Yes you are right, UC500 series are not oficially supported. The problem is - we already have UC520 and phones, so we have nothing to lose. With all this in mind, I wonder may be someone had experience to make it work with some sort of custom firmware or... you know

Hello Damir,

The SPA900 phones are only compatible with SIP, so you would have to configure SIP on the UC in order to register the SPA942 phones.

Please refer to this post for some sample SIP configurations: https://supportforums.cisco.com/message/3330441
