[Asterisk-Users] Audiocodes gateway and asterisk

[Ernest W. Lessenger]

Is anyone on the list using an Audiocodes gateway with asterisk and SIP? 
I'm looking at that platform, but I have a couple of issues:

1) Echo cancellation. The echo that I'm hearing with an X100P is 
unacceptable. Does the Audiocodes do better?
2) Line signalling. I'm using Kewlstart with the X100P, but it looks like 
the audiocodes uses loopstart only. How does this work with voicemail, etc? 
My experience with loopstart on the X100P is that voicemail never stops and 
I end up with two-hour long messages.

Any comments or suggestions?

Thanks,
