The max-connections feature can also be used on the POTS dial peer to limit
the number of calls that can be active on a T1/E1 to a PBX/PSTN if the desire
is to provision all time slots on that connection but limit the number of calls to
a lesser number than the physical number of time slots.
Although this feature is useful in many scenarios, it has the following
drawbacks:
y
Although it provides some protection for the voice gateway egress WAN
link, it provides little or no protection for links in the network backbone.
y
It does not work for IP telephony applications that do not use dial peers.
y
It is limited to simple topologies.
y
It does not react to link failures or changing network conditions.

In Call Manager interworking mode the mechanism of Max call per dial-
