Two PhonePower Problems: Latency & Call Setup Delay (solved)

OK, I got it to work. I put the area code append logic before the logic which appends "1" if the person dials a USA number without that prefix. The order appears to be important.

I wish I had something useful for the Latency issue but I don't. AFAIK: There is no setting on the Obi that can remedy that. That is a Phonepower issue.

RE: latency, I suggest running the VoIP quality test on this website. It uses a Java applet, running on your computer, to accurately simulate a VoIP "conversation" between your computer (and hence, your own ISP) and some far-end server. It's the only meaningful test of VoIP; the typical "speedtest" sites are useless for VoIP traffic testing.

You need to score a 4.0 or better MOS (Mean Opinion Score, dating back to the days when actual human judges listened to and rated telephone call quaity) for reliable VoIP. After running the test, you can examine the factors that go into the score, such as latency, dropped packets, etc. If your MOS is >=4.0, then it's a PhonePower issue. Frankly, there are so many ITSPs available, that if I were you, I'd dump them and find a better one.

If your score is bad, it's your ISP's issue. It's very common for cable internet service to have high speed, while having high packet loss or latency, both of which will wreak havoc on VoIP. It's like driving really fast down a dirt road. You wouldn't notice it when watching streaming video, for example, because of buffering (or really good suspension on your vehicle). You may need to get very agro with your cable company if this is happening, and demand that they come out and test it at your premises.

I ran the test at that site yesterday, and the PhonePower tech support (who were actually quite good) are still running additional tests and sending me the results. Bottom line is that my AT&T Uverse Internet service is producing very good test scores, with an MOS of 4.1, and very low latency.

One interesting thing is that today, perhaps because of phase of the moon or sunspots, the PhonePower latency is absolutely fine, and the call quality is outstanding. I'll have to use it for a few weeks to see if this good quality continues. I just got off a long support call with AT&T on an unrelated issue, and that call involved first talking to the rep on my landline, and then having him call me back on the VOIP PhonePower line. The PhonePower call quality was clearer, louder, and crisper than my landline, using the same handset (my calls go through my Panasonic 6x16 home PBX, so I use the same handset for everything). The latency was low enough that I did not notice it.

So, with fingers crossed, it looks like everything is now working, and at the moment, I am very happy with PhonePower, and their call quality is better than anything I ever experienced in two years of using Google Voice (GV) with my ObiTalk.
