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)

over-subscription

 

Hello All,

 

just throwing this out there. What are people generally using these days
when designing their services, esp. those that require a user to call a DID
to access their system, similar to calling card services. There was a time
when this used to be 50 to 1 for DIDs, and about 10 to 1 for number of
channels bought in SMB with IP-PBX. 

 

I believe this would have changed today and assuming a service is pretty
popular, the ALOCs are longer due to cheaper rates and convenience of
calling. Does anyone have any real world numbers they can share? Is 10 to 1
a good ratio to ensure a user practically never gets a "circuits are busy"?

 

Thanks in advance
