<div dir="ltr"><div style>I am having customer complaints that when they dial an outside conference bridge systems, (e.g. Go To Meeting, etc) or outside IVRs, they are having trouble with the remote system recognizing DTMF tones correctly (e.g. when entering a PIN for a conference bridge). I put in a way in our system to dial an outside number and bypass media for just that call. This seems to resolve the issue, but it is annoying for our customers. </div>
<div style><br></div><div style>My question is how can I troubleshoot this issue? (I have looked at pcap's and from what I can see FS is setting the DTMF correctly) What DTMF settings in FS should I look at? Here is why I currently am using on my external sip profile:</div>
