After years of discussion and months of drafting documents, the National Telecommunications has finally opened up VoIP as a Value-Added Services. Non-telcos may offer it to the public. Read the source: the memorandum circular/final guidelines and the explanatory memorandum.
This builds up on Republic Act 7925 which defined VAS and opened up the Internet industry to non-telcos.
It requires VoIP providers to register with the commission and have an agreement with the telcos which provide the underlying IP and telecom (TDM switching) infrastructure. It requires telcos to allow VoIP providers to make use of their network and give subscribers open access. The telcos have been objecting to this all along since international voice calls have been a major source of their revenues.
