They must arrive a fairly narrow time window and be assembled in the correct order to be intelligible to the recipient. </li></ul>
  17. 17. Fax over IP (FOIP) <ul><li>When VOIP technologies digitize and compress analog voice communication it is optimized for VOICE and not for FAX.

T38 is a protocol designed to allow fax to 'travel' over a VoIP network. </li></ul><ul><li>Convert to computer based fax and choose a VoIP phone system that supports fax. </li></ul><ul><li>Connect the fax machine directly to a phone line and bypass your VOIP system. </li></ul>
