We do support Fax but with the following limitation:

1. Sending fax is supported within CIK network for major cities in Canada but generally Fax over IP is not reliable as traditional PSTN line and CIK has no liability to guarantee fax is always working via CIK residential VoIP phone.
2. Sending fax to oversea might work or might not and it is not guaranteed;
3. HT-502, RTP300, SPA2102 and BX212 are better supporting fax;
4. Receiving fax should be always working but if not working it is due to the originating phone company issue.
