Is there a limit to how many faxes I can send using FaxTalk Fax Merge?
No. There is no limit on how many faxes but there is a limit of how many faxes you can send and receive at the same time. If you are using FaxTalk Multiline Server with multiple fax modems and outgoing lines, you can send more than one fax at the same time (up to a total of 8)
The average transmission time of a single page fax at 14.4kbps speeds is approximately 50-60 seconds not including the actual time to dial the number and the time to answer the call. Therefore, on average you can send or receive about 50 single page faxes per hour with a single telephone line.
