Location-based CAC and RSVP-based CAC

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.
