Hi,

The manual doesnt specify, but what is the difference between conditional and unconditional in the 'Generate progress tone to IP/PBX' on a Quadro ISDN gateway ISDN trunk settings?


Thanks.

AS far as I am aware, the unconditional means the system will always generate the progress tones...

Hello

Here are the definition of None,Conditional and Unconditional in the 'Generate progress tone to IP/PBX' (for incoming calls from PSTN/PBX of course):
- None configures the system to send ALERT messages without the Progress Indicator information element (IE). It is assumed the carrier will play its own progress tone.
- Unconditional configures the system to send ALERT/PROGRESS messages with the Progress Indicator IE. With this option, the system will send its own progress tone.
- Conditional configures the system to send ALERT/PROGRESS messages with Progress Indicator IE. With this option, the system will send its own progress tone only if there is no early media (180/183 with SDP) from the called party.
