Yes. You will require a feature named “Call Forwarding” added to your existing fax number – your existing telephone service provider can set this up for you. Once the feature has been added, you can forward all calls made to your existing fax number to your new SRFax fax number. Your existing fax line can be used for outgoing faxes and as a spare line but it will no longer receive faxes. Some phone lines have a call forwarding feature already available so check with your service provider. See your provider’s documentation or Contact Us and we will be happy to help.
