I have a couple of questions:
 
-Does the Built-in Bridge (BiB ) recording feature (not supervisor monitoring) support duplication of iLBC media streams?
-Is there anything special that needs to be in the SDP for this on the SIP trunk? (mode=20, mode=30, etc).
 
Thanks!

Yes, most of the TNP and RT  phone models do support iLBC . see ToI in the wiki page referenced below for specific phone  models . If the recorder also  supports iLBC , you are good .

If recorder device does not support iLBC  - it is a code mismatch case . In case of codec mismatch between phone BiB and recorder , CUCM will have to insert a transcoder . CUCM Transcoder did not support iLBC in CUCM 6.x timeframe . not sure what version  you are interested in .

 
Is there anything special that needs to be in the SDP for this on the SIP trunk? (mode=20, mode=30, etc).
Please eloborate on this question . what 'mode' are you talking about here  ?

Thanks. We determined there was a bug in Call Manager that prevented this from working, and Cisco fixed it awhile back.
