The impact of the switch to All-IP on sending faxes

The switch to All-IP has numerous implications for your telecom services, including fax

Voice over IP technology is optimised for voice communicationsThis means that fax and other services added to the voice bandwidth can no longer be assured.

After the switch to IP, although analogue faxes can still be used in theory, POST cannot guarantee their delivery. Support for fax delivery problems will no longer be possible.

This change of technology from switched telephone networks to All IP networks presents numerous benefits, including new features such as landline/mobile convergence in our LuxZone and CloudPBX packages. However, faxing and the use of certain other services will only be possible in a very limited way.

As the technologies and the operator interconnection interfaces used on the public switched telephone network (PSTN) are identical, problems with the reliability of fax delivery are identical for all operators.

All telecom stakeholders (suppliers and operators) have agreed to gradually change the switched telephony technologies of most European countries over the next few years. Regulation ILR/T17/9 ILR of 9 August 2017 reflects the consensus on this matter among all Luxembourg stakeholders.

Limitations are independent of the type of connections that are now used (BRI, PRI, POTS, SIP Trunking), whether on POST Telecom’s Voice-over-IP platforms or the old switched telephone network.

Although POST Telecom understands the legal value of faxes in some industries, there are alternative solutions on the market for validating documents with an electronic signature.
