Hi folks,
If anyone here has worked with VoIP PBX systems (after all, I'm told, it's "just a computer"), can you answer this question?
Is it an "industry standard" for these systems to fail to pass through basic signaling from the PSTN (public switched telephone network) to the ears of people using the phones?
We recently purchased such a system and, while it transmit a "ringing" signal when we dial a number outside our system, it does not transmit "busy" signals when the line we dialed is engaged. It also does not transmit fax tones when we dial a fax number (useful for diagnosing faxing problems), nor does it transmit recorded audio from a phone company, such as "The number you have reached is no longer in service" (useful for what should be obvious reasons).
The vendor claims that our expectations that a PBX phone system should do these things are unrealistic, and that if we want it fixed, we should pay for "support".
My contention is that these failures are product defects that should be repaired under warranty.
What is your experience on these things?
Thank you very much.
