MP-11x & MP-124
The device also supports "double call hold" for FXS interfaces where the called party,
which has been placed on-hold by the calling party, can then place the calling party on hold
as well and make a call to another destination. The flowchart below provides an example of
this type of call hold:
Figure 24-1: Double Hold SIP Call Flow
The flowchart above describes the following "double" call-hold scenario:
1. A calls B and establishes a voice path.
2. A places B on hold; A hears a dial tone and B hears a held tone.
3. A calls C and establishes a voice path.
4. B places A on hold; B hears a dial tone.
5. B calls D and establishes a voice path.
6. A ends call with C; A hears a held tone.
7. B ends call with D.
8. B retrieves call with A.
