[asterisk-users] Common/Reasonable Assumption on DID/Channel over-subscription

[A E [Gmail]]

I suspected as much :)

Well, it IS a calling card; people call an access number, dial an
international number.

Assuming typical ALOC to be 8 mins which is seen quite often in
International calls esp. in ethnic communities, and since the service
hasn't launched yet, it's hard to tell what the incoming traffic will be
like but in order for us to purchase the channel packs, we do need to
figure out the ratio of over-subscription we can use for the number of
channels to buy so while I understand it's a little vague, just wanted to
hear from people who're running similar services and what is their actual
channel usage and if they have consciously designed it using an assumption
for this ratio or they just buy more channels and/or DIDs looking at
historical data (or customer complaints)
