Fax

[rarneyjr14]

If my modem has two phone jacks can one be used for my landline and the other my printer/fax/scanner? Or will I need a separate number for the fax?

If you want to use the second phone jack as a dedicated fax line, you need have Comcast add a second phone number. You should find that they have a no-frills offering at a reduced price for just this purpose.
