MPLS & RSVP

[ajentilucci]

We are getting ready to migrate onto AT&T's MPLS network. One of the action items we have down the road is to enable RSVP for call admission in our CallManager environment. I hear AT&T's MPLS switches may not support the RSVP protocol. Anyone have any experience with this?

Dont understand much of nitty gritties of voice. But as far as for admission control to work, you PE should understand and respond to the path and resv messages within a VPN for admission control coming form each CE site.

Afaik, this is currently not supported by any vendor (probably not a standard yet).

Although its work in progress, here is a draft for the same.
