4 Advanced Functions
4.1 Call pickup
This allows a third party to answer a call by dialing a code. For example: A calls B, but
there is no answer. C can go off hook, dial a code plus B’s number, and pick up the call.
The following chart shows how to configure this in the dial peer screen.
*1* is the code. After saving the above configuration, C can dial *1* plus B’s phone number
to pick up A’s call. The prefix can be set to anything the user desires that does not interfere
with other dialing rules.
4.2 Join call
This allows a third party to join an existing call. For example: If B and C are on a call, A can
join by dialing a code plus the number for B or C. This assumes that B or C also support
Join Call.
The following chart shows how to configure this in the dial peer screen.
*2* is the code. After saving the above configuration, A can dial *2* plus the number for B or
C to join B and C’s call. The prefix can be set to anything the user desires that does not
interfere with other dialing rules.
4.3 Redial / Unredial
If B is on a call when A calls, A will get busy tone. If A wants to connect to B as soon as B
is available, he can use the redial function. To use this feature, A dials a prefix and then B’s
number.
When the redial function is activated, A will check B’s calling status every 60 seconds.
When B is available, A’s phone will ring. When A goes off hook, the phone will call B
automatically. If A does not want to call B, the redial function can be cancelled by dialing a
prefix plus B’s number.
*3* is the redial prefix code. A can dial *3* plus B’s phone number to activate the redial
function.
*4* is the unredial prefix code. A can dial *4* to cancel the redial function.
The user can select any prefix as long as it does not interfere with dialing rules.
