<p class="MsoNormal" style="margin-bottom:12.0pt">Double check that the config took the payload type change to 100. That's the default for NSE's and you cannot normally change the payload type value unless you change the NSE value to another value first.<br>
<br>
Don't have a CLI in front of me, but it's similar to:<br>
rtp payload-type nse 99<br>
rtp payload-type nte 100<br>

<p class="MsoNormal" style="mso-margin-top-alt:auto;mso-margin-bottom-alt:auto">As mentioned above the yellow highlighted portion of the SDP’s is where we can see a mismatch in our payload type. You can see the telco is sending 100 and we are sending 101.
To resolve this issue you have to remap the rtp payload type for signaling and telephony events. Here is the commands I had to run to send 100 as our NTE to match what the provider was expecting…<o:p></o:p></p>

<p class="MsoNormal" style="mso-margin-top-alt:auto;mso-margin-bottom-alt:auto">Because the signaling is defaulted at nte 101 and nse 100 you have to remove 100 from nse by assigning it a random unused value before you can assign 100 to nte. See this image

<p class="MsoNormal" style="mso-margin-top-alt:auto;mso-margin-bottom-alt:auto">The problem is that when we dial into this one external number and press 1 to select option 1, it doesn’t seem to accept the digit. If we dial into that same number from anywhere
else, it works fine. Having said that, I can dial into other numbers from the system and have no issue at all with dtmf. Any ideas of what this issue is?<o:p></o:p></p>
