<div dir="rtl"><div dir="ltr">Hello,</div><div dir="ltr"> </div><div dir="ltr"> I had for a long time a Cisco SIP-E1(with Q.sig) gateway which caused me much grief with DTMF; it works partially OK with INFO but not with RFC-2833. I filed a support call with Cisco, as its debug shows that it receives and detects the RFC2833 but nothing is sent to the E1 side.</div>
<div dir="ltr"> </div><div dir="ltr">The last conslusion of Cisco's support is that I have to enable transcoding but they coouldn't find how to enable it in my configuration. I now have an Audioodes Mediant-1000 on loan which does RFC-2833 without any problems...</div>
<div dir="ltr"> </div><div dir="ltr">The only problem I've found so far with the AudioCodes is name passing via E1/Q.sig at the ringing phase (we use it to connect our Freeswitch to our Nortel PbX).</div><div dir="ltr">

<div><br></div><div>I spent several very very painful days trying to get RFC2833 to work, using FS to try and generate the tones itself. I ended up with all sorts of codec mismatches, delay,distortion and some really mangled DTMF tones…</div>
