How to enable the subject technology in order to block to calls in case of oversubscription.

It is not just enabling these, first you need to figure out which one you want to use, second you need to plan carefully, calcuate your bandwidth, etc.
Please check out latest SRND for great explanations on both and some configuration examples:

Hi,
Your original question asks about blocking calls due to
oversubscription of bandwidth.
This is easily carried out by setting the correct bandwidth at each LOCATION.
1 x G729 Call = 24 K
1 x G711 Call = 80K
So lets say the link between LOCATION A and LOCATION B has a usable
VOIP bandwidth of 100K
This will allow 4 x G729 Calls or 1 x G711 Call
Any calls above these limits will be rejected with an INSUFFICIENT BANDWIDTH legend
appearing on the phone making the call.
Remember to make sure that the correct codecs are slected between regions.
