[Asterisk-Dev] Voicetronix Openline cards

[Terence Parker]

This too probably belongs in asterisk-users, but since it originated 
here....

We used a Voicetronix OpenLine4 card for a while back when the asterisk 
support was still an unofficial knock-up and bundled with Asterisk - 
and I can certainly say it resembled very much to be software based. 
Back then we couldn't utilise more than one VPB channel at a time - any 
more and the conversation on any one line would just be an unacceptable 
quality.

Since Voicetronix have released their own interfaces to Asterisk, this 
has much improved - the card could at least be classified as "usable" 
or "acceptable" ... though we're still far happier with the results 
generated by our Vegastream PSTN gateway. I don't know whether this new 
improvement is still 'software' or 'hardware', but in any case it's 
definitely acceptable - and at the very least Voicetronix appear 
committed to improving their Asterisk support, so you could expect it 
to work flawlessly in the future.

That said, I still prefer external units.
