eFaxing is actually a bit simple in the complexity. If you can write an email?, and attach .pdf files to the email, then you can use eFaxing. Assuming you have an eFax account ($10/month + outgoing pages), then you can use the eFax system. When receiving faxes, the phone number will collect the fax, convert it to a .pdf file, and email it to your email address. You can open the .pdf file, and read the fax. If you need to print it, you can do so easily enough. If an incoming call is a voice call, then the system will send the caller to your unified voicemail. Now when you wish to send a fax, you would compose an email. The TO: will be the telephone number @pcs1.ws. For example, to fax 8553292377, you would send an email to 18553292377@pcs1.ws. Make sure the FROM: is from your recognized email address. The SUBJECT: is the subject of the fax, and the text in the body is your cover page. You would then send the email. The system will then dial the number, and send the fax. Once the fax process is complete (or failed), you would receive an email with the results of the fax. Outgoing faxes are 10ยข per page, and cover page counts as part of the fax.
