Just to make it clearer, here's the problem

My Voxalot accounts are 968031 with Pfingo1 registered and 968032.with Pfingo2 registered. There are more provider resitered but for simplicity sake just consider that.

1 - If calling 968031 -> Pfingo1 -> Pfingo2 -> 968032 the quality is good
2 - But if one bypassed Pfingo and call direct 968031 -> 968032 then quality is bad

The end point ISP connecting the 9680xx in each case are the same, how could it be that going the long way round via Pfingo can produce better quality than going direct from Voxalot to Voxalot? that is why it is perplexing.

Here's some more example.

1 - At each end a Linksys 3102 is used to register with Voxalot. I sit in Vietnam with a telephone connected to my Linksys 3102 registered to Voxalot 968031 and call directly to 968032 registered via a Linksys 3102 in Singapore, my wife answered the phone and invariably complained of unintelligible speech.

2 - So we both hang up and I called Singapore again by activating a Pfingo registered with Voxalot 968031 and called another Pfingo registered with 968032, the conversation is then much clearer and we can talk for along time.

How can we explain that? surely I would have expected that the Voxalot to Voxalot call, cutting out Pfingo, to produce the clearest sound, but the reverse is happening which I can't understand
