Hold in SLS mode

Last Updated : Mar 25, 2020 |

Using the Hold feature differs by user and by phone type, and the same is true of the Hold feature in Standard Local Survivability (SLS) mode. Some users return to a call on Hold by pressing the Call Appearance button, however, CM has an administrable parameter that allows users to release a call on hold by pressing the Hold button a second time (if only one call is held). The Hold feature also works differently in DCP and IP phones and analog phones in the survivable mode.

The Hold feature in SLS does not support:

  • Music on Hold

  • Local mute on analog phones

  • Specialized treatment of E-911 calls

  • Call Hold indicator tones
