Reply To: a-800 quntum , configration


Take a look in your PSTNtg 1
group, see what value do you have on Answer delay timeout.

That is the time that the Quintum will “listen” for an answer before starting the billing.

This is how it should be on a gateway with no wait:

Cas Signaling Type = loop start fwd disconnect(6)
Cas Orientation = user(0)
Dial Tone Detect = yes(1)
Dial Delay Timeout = 1000
Answer Delay Timeout = 0
Flash-Hook Signaling = no(0)
Supervision = none(0)
Caller Id Detection = no(0)
dtmf-ontime = 100
dtmf-offtime = 100

That means that the quintum will not give you any “grace” period. The soonest that the quintum connects the VOIP side with the PSTN, it will signal back to the billing that the conversation started,regardells of the conversation being detected or not.

In order to avoid billing persons for a busy tone , or short calls that went nowhere, you need to setup the grace on your billing system.

If you use both variables, you are adding the efect.

30 seconds delay on quintum, and 30 seconds grace on billing means that you may loose up to a minute per call.

Give it a try. If you need assitance making few test calls, give a holler.
