A multicall line is an appearance of one extension number on two or more telephones. This extension number can be for another Mitel telephone or an industry-standard telephone. When one appearance of a multicall line is in use, the other appearances are still available to make or answer calls.
Call direction, ring and secretarial variants can be programmed independently for each appearance.
There can be up to 64 appearances of any one multicall line on a given Mitel telephone.
Conditions
The following conditions apply to this feature:
Direction, ring and secretarial variants can be programmed independently for each appearance.
It can appear on several Mitel telephones.
There can be up to 64 appearances of any one multicall line on a given Mitel telephone (64 IP sets, or 32 IP and 32 DNIC sets).
The secretarial operation feature description in this section only applies to multicall lines.
When a multicall line is called, there can be as many callers ringing the line as there are appearances that are free to be rung. When a caller rings the line, the first appearance of the called line is rung on all Mitel telephones where the line appears. The next caller of the line makes the next appearance on all Mitel telephones (the next level or tier of appearances) ring. On a single Mitel telephone, the appearances of a multicall line are rung in order from lowest key number to highest key number.
If a line is a phantom line with a programmed PLID, the line can be called. Telephones with multi-lines can be called whether the line card is plugged in or not.
If the multicall line appearance is on the prime line, or on a non-prime line and COS option 509, Display Caller ID for non-prime lines is enabled, the CLID is presented automatically on the set display. If the multicall line appearance is on a non-prime line and COS option 509 is disabled, the CLID can be displayed by pressing Superkey and then the ringing line. Note: COS option 509 requires Feature Level 3 in System Option 102.
