Not at this time.
This is called Call Admission Control and there's no concept of it at this
point.
Personally I believe this belongs at the network layer rather than at the
application layer with hard limits. Cisco had done some work around this
early but I'm not sure it's current state in their routers (
http://www.cisco.com/en/US/docs/ios/solutions_docs/voip_solutions/CAC.html#wp941119
).
There's also a RFC that's being worked on around this.
http://tools.ietf.org/search/rfc5865
Hard limits are kind of silly. Say for instance I have 5 users at branch A
who decide to fire up video calls versus G.729 calls? So now each one is
consuming 256K to 320K instead of 20K. Have I solved anything? Let's look
at the reverse also. If I had 5 users on the phone at Branch A and my
limit is 5 calls. If I have a full T there with 1.5 Mbps and I'm only
using 400 Kbps for voice and only another 400 Kbps for data why wouldn't I
want to allow another call instead of delivering reorder to my end user.
Am I delivering good customer service?
Clearly an intelligent mechanism that understands the dynamics of the LAN /
WAN needs to be implemented. I think that the above example highlights
that this really does belong at the network layer and not at the
application layer.

Post by Bryan AndersonIs there a way to set the number of external calls a particular branch or
group can make through a gateway?
Branch A = 5 calls
Branch B = 4 calls
Branch C = 10 calls
