Please be aware: CME does not officially support any 3rd party SIP clients. CUCM does, however. Most clients will still work, but it's just not guaranteed.

Q. Can I deploy third party SIP Phones with these UC Bundles?

A. Today third party SIP phones are not supported with CME on the ISR or UC500 series. Customers wanting to use a third party SIP phone even without TAC support need to purchase a SIP Third Party phone license (SW-CCME-UL-3PSIPS= or SW-CCME-UL-3PSIPM=).

So, for example you buy a Linksys phone (a Cisco brand) - if doesn't work Cisco will not support you, but you have to pay anyway $150 for each single-line phone, or $300 for a multi-line.

thank you very much for your answers.

however i don't understand the story of these licenses?

-when i buy a license, do i get a serial key (for example) that i write some where in the ISR? or is it just a legal way to use phones?

-if i will not buy licenses, will the SIp phones work ?
