Sounds like you had a bad experience with SIP trunks southlander. Bummer. They are such an awesome facility for features and disaster recovery.But as you unfortunately found out, it's not about bandwidth at all (although you need enough for your total simultaneous conversation count), it's about the QUALITY of the connection to the ISP. I've met hundreds of misguided IT guys that think you can throw more bandwidth at the problem only to find out that VOIP still sucks. DUH!!!
If you have a 200k (yes k) connection with two calls on it, and that connection is pristine (no delay/jitter/packet loss) it will be perfect compared to a 5meg (yes meg) connection with two calls on it but having over 3% packet loss. Quality.
It's worth another try southlander. With the right connection you'll be better off.
Now we're making sense lol
Skype seems to have A LOT of packets loss getting worse as the call progresses, BBMV has none, the more I think about it, it seems even better then a regular long distance cell call. It's louder and clearer, I have to turn my volume down a few clicks every time.
Could RIM be using any of it's UMA technology in this?

This would suggest that the media packets are taking a different and better path for BBMV.
Or... It could be that PC or the iPhone is having connectivity issues.
Does BBMV work over cellular?
I think I recall reading that it does not(RIM appeasing carriers?)
One of the characteristics of UMA is seamless handover.
This means that you could start a call on you WiFi and walk out of range of your WiFi and switch to cellular with no noticeable impact on the call.

Not exactly a fair comparison since the tests are done on different hardware. Ideally we should do them on the same device, but we can't do that, can we, since there's no Skype on BB.
Distortion from Laptop mikes could be an issue, perhaps? You can try recording your voice via the laptop mike and seeing how good it sounds on playback.

Could be something as simple as the codec that RIM uses compared to the codec that Skype uses to packetize the voice. Some codecs are much better than others.

I thought I would try out the BBM Voice yesterday on a buddies phone. I have to say the call quality was extremely impressive. I have also heard that if you are calling someone cell to cell, and both have BBM voice (and both are in WiFi range) , the system recognizes this and places you both on BBM voice. Very cool.
