VOIP (PennyTel) - Incoming Calls - Problem

Posted on August 11th, 2008 by Amit

I have been using VOIP (PennyTel) now for nearly a year. Initially, this was only my outbound ISD solution. However, recently, upon changing my ISP and moving homes, I decided to pilot this as a primary telephone service for all needs:

  1. PennyTel to local/interstate/international PSTN (outbound)
  2. Local/interstate/international to PennyTel (incoming)

#1 was tried and tested, so I had absolutely no trouble with that. #2 was where I had one problem.

People had to make several attempts to get through to our PennyTel VOIP line. And when they did get through, the line was unreliable, and had long silence patches

After spending numerous hours with PennyTel technical support and going through my VOIP gateway, Linksys/SPA3102-5.1.5(GWa), configuration options, I figured out the following:

The “PSTN Line” option was not configured properly.

On this tab, I selected the following options:

Enable PSTN Line = yes
Detect VOIP Long silence = yes
Preferred codec = G711a

G711a is the non-USA codec that translates the traditional analouge voice to a 8khz/8bit or 64kbps voice channel.

Voila, the incoming PSTN phone calls have never had a problem since!

    However, what I fail to understand is that why did PSTN to PennyTel phone call work (albeit inconsistently) earlier? Spooky.
