Fax Over IP
Fax transmission is a key application for many enterprises. Financial institutions, banks, government offices, law firms, and many others still use fax machines to transfer a multitude of documents on a daily basis.
Moving from TDM-based PBXs to IP telephony, enterprises tend to gradually replace existing analog and TDM phones with IP phones. However, fax transmission is still a challenge and requires a reliable solution for connectivity with the new IP telephony infrastructure. When it comes to fax service, an enterprise connected to a SIP trunk may suffer from poor quality or even complete failure of its fax service. This issue is a result of differences in the fax protocols used by the SIP service provider and the enterprise.
