DM15 VistaPlus Troubleshooting: Call Announce tones cannot be heard
Call Announce tones cannot be heard.
A call announce tone, by its nature, is a sudden noise. Because the VistaPlus looks for sudden increases in sound compared with the preceding sound level, if the VistaPlus has had low volume input for a while (ie idle time before a new call comes in), it is more likely to treat a call alert tone as a startle event, even if the absolute sound level of the tone is not that high. Your telecoms department may be able to adjust the tone to reduce the likelihood of this happening.
