Mitel 5220

Asterisk Asterisk Support
1

Hello All,
I got my hands a couple of Mitel 5220’s they connect to asterisk and work great. The only problem is DTMF is not working correctly. Is there a feature that allows me to change it VIA Sip info? I searched and dont see anything.

Thanks

You can set the DTMF payload type in the Media Configuration section of the set Web configuration page.

Set DTMF Type to Outband, choose the DTMF Payload type (Asterisk default is 101). Configure the DTMFmode = rfc2833.

Lots of info and latest software on Mitel’s web site: sipdnld.mitel.com/
