1. Does SIP provides capabiltiy to choose different codecs available at
endpoints   
    for call?

this is done with SDP carried within a SIP message

2. How can bandwidth be controlled by external entity for SIP based call ? 

I do not think it can be done with SIP, you can do it with H.323
(I am assuming by external you mean a non-endpoint)

thanks,
mike feldman
