With SIP terminals and if the communication server is connected via an SIP provider to the pub-
lic network, the tiresome task of entering end of dialling characters can be elegantly bypassed
using an external numbering plan (see "Call to the public network with external numbering
plan", page 201.)
9. 6. 4 Call waiting
Call waiting is used to notify an internal, busy user B that another user C is waiting to
talk.
User B can choose to take C’s call (and put the original call on hold, end the original
call or set up a three-party conference) or reject it.

Detailed Description
Tab. 191 Call waiting
If B is in an outside call, call waiting will only work if this feature is enabled for outside
calls too (Call waiting and intrusion on exchange connection).
If the announcement service is activated and user B does not respond to the external
call waiting, the calling user C will obtain a greeting message.
