Please be gentle, as I haven't worked with IP Telephony for 3 years.
I am trying to figure out some usage stats for our VOIP calls over IP Trunks, not PRI/PSTN connections. We do not have any 3rd Party Call Accounting, so I know my choices are rather limited. Also, this system is being phased out in a year, so we won't be able to put any Call Accounting in.
So basically, I need any usage stats I can get for IP-based WAN calls.
Thanks in advance
