Created by: Chris Anderson on 25-03-2009 09:33:45 PM 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 ? Please use the below wiki page as reference. As always, the documents contained in this wiki are Cisco-internal-only and should not be shared with external .
