the caller.
■
If a ring group member puts a call on hold, that member can
receive other calls.
■
A ring group caller on hold will hear ring group Music On Hold.
■
If the telephone has Hands Free enabled, an incoming call to a ring
group will not be picked up automatically.
■
An external call to a private user (someone not in the ring group) can
be transferred to a ring group.
■
Both attended and unattended call transfers are allowed for calls to a
ring group or from a ring group.
■
Internal and external callers that are forwarded to voice mail can leave
a message and navigate through the voice mail options.
■
If a ring group call is routed to a voice mailbox or Auto Attendant call
coverage point but the routing fails (for example, because no ports are
available), the call is requeued for the ring group.

Each time a call is put back in a ring group queue, it is treated like a
new call.
Emergency
Telephone Number
Dialing Service
3Com telephones provide the capability to dial an emergency telephone
number even when the telephone is not logged in to a system. The
telephone must be properly configured, connected to an operational
system, and the region must support this service. If the system is not
operational, an emergency call can be routed (optionally) directly through
a PSTN media gateway. Contact your system administrator to determine
the appropriate emergency number for your region.
