VoIP plays an important role in reducing monthly telephone bills. This is because Voice over IP uses broadband lines instead of coaxial lines, thus reducing communication costs. Because of the productivity and cost benefits, both businesses and individuals are increasingly using VoIP services for their daily communications. This packet-switching technology allows users to access video, voice, and data over the same IP network. In addition, this innovative technology can also be used to send faxes – sending faxes via VoIP is now possible at significantly lower rates than traditional landlines.
Sending faxes via VoIP differs somewhat from the usual procedure via the public switched telephone network (PSTN). However, there are some initial difficulties with this method that can usually only be resolved after several attempts. When the fax audio is digitized into compressed IP packets, packet loss can occur, resulting in faulty faxes, error messages, or even dropped calls. In contrast, faxes sent via Fax Codec reach their destination efficiently and with minimal packet loss.
Key Points for sending VoIP Fax
Before sending a VoIP fax, users should consider the following important points.
- The user should set the baud rate to 9600 and disable the wrong connection mode. In practice, the baud rate is kept low so that the fax arrives at the recipient slowly and without error.
- The user must choose a provider that supports T.38 – T.38 with a developed audio codec VoIP faxing with T.38 – T.38 offers redundancy in the RTP stream and thus a more detailed and clearer image, accompanied by stability the user can use the RTP stream to send and receive faxes in batches of up to 10
- The user must set the batch processing to less than 10 ms. The more headers the RTP stream contains, the lower the jitter and jitteriness.
The stability of the Internet connection is an important factor in the success rate of faxes. Maintaining a stable connection requires monitoring speed tests and detailed analysis of the connection.
Even if all the above recommendations are applied, users may still not be able to send faxes via VoIP. In this case, it is best to contact the solution provider, as the problem may be related to routing. The routing problem can be solved on the solution provider’s website.
It is recommended not to use satellite or radio connections for sending faxes, as they are unpredictable. In addition, such connections cause a lot of delays that prevent the VoIP fax used from working properly.
