When Ring Groups are programmed, calls ring multiple telephones, stopping when any one of them picks up. You can program a ring group to ring all extensions simultaneously (Ring All) or one at a time (Cascade Ring), starting with the first member of the group and continuing to other members in the order in which they are programmed to the group.
Other features of Ring Groups:
calls queue if there is no free member to ring
calls unanswered within a specified period are sent to the group's designated overflow destination
member phones with large displays show both the group and caller name and number when the group is rung. Small-display phones show the ring group only.
The following types of numbers or devices can be programmed as a ring group member:
Any type of broadcast group A directory number programmed to appear on multiple devices constitutes a broadcast group. There are two types of broadcast groups: Non-Prime Line and Prime Line. A Non-Prime Line group is a directory number programmed on one or more devices that is not the prime line on any device. Up to 32 appearances of this number may appear on one or more devices. A Prime Line group is a directory number programmed on button 0 of a phone. Up to 32 appearances of this number may appear on one or more devices.. This includes:
multiline set prime number
non-prime line numbers
key system numbers
multicall numbers
single line sets
a night bell
The following directory numbers cannot be programmed as a member of a ring group:
extensions with the "voice mail port" COS option
extensions with the "Recorded Announcement Device" COS option.
attendant consoles and console LDN numbers
Hunt group, Agent group, Path, Ring Group, Suite and Linked Suite pilot numbers
ACD Agent IDs and ACD set DNs
ARS digits
a pilot number of another ring group
RDN numbers
a pilot number of a Personal Ring Group
Users cannot place callbacks or camp on to a ring group.
Ring Group capacities are as follows:
Specification |
Maximum |
Maximum number of ring groups |
176 |
Maximum number of members per group |
32 |
Maximum number of ring groups in which a device can be programmed |
8 |
Maximum number of simultaneously ringing members
|
172 200 (see Note) |
Maximum number of calls that can be queued to any or all ring groups |
84 |
Note: The system can ring a maximum of 80 broadcast groups in unison. The maximum number of appearances in all 80 groups that it can ring is 172. Of the 172, up to 80 single-line appearances can be rung with the remaining appearances being multiline sets. Devices in excess of these limits will not ring. Error logs may also be generated during the call.
The following directory numbers can be programmed as a ring group's overflow destination:
station DNs
broadcast group DNs
attendant console DNs
system speed call number
hunt group DN
ring group pilot DN
Note: The system does not check for invalid destinations.
Ring group calls that are forwarded to an overflow point will follow call forwarding but not system rerouting programmed for the overflow point.
Call handling when the overflow destination is unavailable (or not programmed) and does not have call forwarding enabled depends on the state of the call:
If ring group member(s) are ringing, the call continues to ring until the caller hangs up or a member answers, or until the applicable the COD ringing timer expires and the caller hangs up.
if the call
is queued to a ring group, the call remains queued until the caller hangs
up or member(s) start to ring
Calls
transferred to a ring group that go unanswered either recall back to the
transferring party or go to the group's overflow destination. The timer
that expires first
Call forwarding and system rerouting cannot be programmed against a ring group's pilot number.
A ring group can be a call forward or system reroute destination.
Call forwarding or system reroute programming against ring group members is ignored for ring group calls. However, if ring group members have Call Forward No Answer (CFNA) programmed, the "Forward" softkey prompt is displayed on ringing members' phones. Pressing the softkey will forward the call to the member's CFNA destination.
Phones that support the Call History application (5xxx IP Phones, 5235 IP Phone, Your Assistant) accumulate logs for ALL ring group calls for each ring group in which the phone is a member. To avoid this, program a non-prime line appearance on the phone, and then program the non-prime line to the ring group. The following scenarios will generate missed call logs on devices that support the Call History:
a ring group caller abandons (hangs-up)
a Ring All group caller calls the phone and is answered by another member
a Cascade Ring group caller rings the phone and subsequently rings another member
When there are calls ringing or queued to a ring group, the first member to become available is offered the oldest ringing or waiting call. If a member belongs to more than one group when it becomes available, it will get the call waiting longest of all groups.
Calls queued to a ring group and calls ringing a ring group will not survive a failover. However, queued and ringing calls to a ring group may survive a failback.
Calls can be parked to a ring group pilot number. Parked calls do not ring the members of a ring group.
Ring groups are not supported by the Group Administration tool.
