Re: CME --> SIP Trunk DTMF Issues

Thanks Nick!

I do see the following when I actually press buttons. This would be an
example of me pressing the "5" digit hence the Evt: 5. I see the packet
type is indeed 101 and that it is sending (supposedly) I guess maybe a
packet capture will be next

*Oct 1 2009 06:12:42: s=DSP d=VoIP payload 0x65 ssrc 0x535A4E81
sequence 0x7408 timestamp 0x273D800
*Oct 1 2009 06:12:42: Pt:101 Evt:5 Pkt:04 00 00 <Snd>>>
