I purchased some g729a licenses from digium but found ulaw to be just as good. If anyone sees anything to fine tune here please feel free. Hope this helps someone!

Nice, Have a star.
Asterisk is a product we are being asked about more and more, my concern is it not a commercial product so when S*&t hits the fan who you going to call? But hey you get what you don’t pay for.

We are also trying to use Asterisk with our IPO's.

The problem we have is that the DTMF signals are not been understood by Asterisk...so we cannot dial numbers etc.

Can someone please provide some sample config's that may alleviate this issue.

Thanks.

pay $800 for the business version and call digium

Do you have "Outr of Band DTMF" enabled on the VoIP line of the IPO?
if so try turning it off

I cant help any futher as I not played with asterix (yet)

I have tried this setup and dialing works, however using a SIP or IAX phone on my computer, I don't hear anything on both sides. Trying a different codec than ulaw results in a conversion error. Any ideas?

 

[tbui99]

We're getting an error message on the Asterisk side when we try to bridge SIP with the H323 codec. Do you have some code that addresses that? The call actually reaches the IP Office side and passes all the right info, but the minute that the call is answered, the error occurs. Thanks!
