Mitel MiVoice Business/MCD/3300 / Re: Possible SIP DTMF Tone issue

Hi Dutch,

Thanks for the quick response and your support.  Is the RFC 2833 configurable within the 3300 as I'm struggling to find where to locate this?

Mitel MiVoice Business/MCD/3300 / Possible SIP DTMF Tone issue

« on: April 26, 2016, 06:52:35 AM »

I am no expert and I am struggling to get a working solution from our Mitel reseller so I'm hoping for some on-line help.

We currently have a Mitel 3300 MXe with a separate Mitel Border Gateway.  I have no issues with the 5304 IP Teleworkers which are running the G.729 codec when we  exit out on ISDN30.  Just to let you know that the Teleworkers are connected to a Thuraya satellite bearer which has packet loss and high latency.  When I change the 3300 config so that the Teleworker exits via a SIP trunk to our SIP provider Gamma I believe I have DTMF tone issues.  When I try and type digits into the keypad for a password I hear that the digits are not recognized.  Sometimes it works, sometimes it doesn't. 

Has anyone come across this issue before?  I'm hoping that a setting can be changed on the 3300 but I'm guessing this could be down to the SIP provider.

Thanks
