A customer has an internal "First Response" capability in their plant that is called for some emergencies. The First Responders are called via the paging system.
Their old phone system allowed them to press a key and use a continuous DTMF tone as an "attention getter" during these calls. Their new CME won't do this, accessing the paging system via ATA-186 port. The short duration of the tones doesn't do much for them.
I've duplicated it myself and can find no way to accomplish what their old system did.
Has anyone had a similar issue that would have a suggestion, or a workaround, that might help?
