Cisco 7821 / 8851 codec support

Hello,

Which codecs are supported by Cisco 7821/ 8851 phone?

In the Data Sheet I can see the following info:  "G.711a/μ, G.722, G.729a, iLBC"

 

In the Admin Guide I can see:

"A Cisco IP Phone, like other network devices, must be configured and managed. These phones encode G.711a-law, G.711 mu-law, G.722, G.729a, G.729ab, and iLBC codecs,and decodeG.711 a-law, G.711 mu-law, G.722, G.729, G.729a, G.729b, G.729ab, and iLBC codecs"

Which set of codecs is supported by these phones?

Regards

Piotr
