a lot of delay on rogers data sim on samsung ace

[avengine]

I am testing dell voice in samsung ace, in the app from google play and testing calling from my home voip line to it, when it is using wifi, in/out is ok, when I switch to 3g using rogers data only plan, I can see the E, I think this is Edge network and I have 3 signal bar, but the audio is very bad, no way to hear it, if I do the same thing in ipad2 3g, it is ok.
how critical is the phone for using this app, is there some reasonable device should be use.
the android os is 2.3.6
thanks.

You'd want to have at least a 3G mobile data connection to use Dell Voice. If you're only getting an Edge connection then that would explain the poor quality calls and cut outs. Edge was pre-3G and isn't fast enough to suitably sustain a VOIP call.

EDGE can have a latency of a couple of seconds at times. That is walkie talkie VOIP! Also, EDGE does not have much upload or download bandwidth, so the standard Dell Voice app will probably overload it. You would need a dedicated VOIP application with a high compression voice codec, and even with that, the voice quality would still not be optimal.

3G is not much better, it can have a latency of 1/2 a second or more, which is noticeable on the call.

Rogers also has a really awful NAT, so you might not get incoming calls through SIP VOIP, or one way audio.

I hear LTE supposedly solves a lot of these problems, but I have not personally tested that.

Are you actually using Rogers, or one of Rogers' MNVOs? I know Speakout users, (Speakout uses the Rogers network), have had issues with being dumped to 2G in busy metropolitan areas. But since Speakout customers were only promised 2G, they have no right to complain.
