It appears we have found an issue in our recent build of the MizuPhone applet. Regardless of the dtmfmode parameter, Mizuphone sends DTMF as SIP Info events instead of RFC2833. When this happens our server sends a “405 --Method Not Allowed” response and Mizuphone ends the call as a result.
Can you please look into this?
To Test:
Make an outbound call
Hit a single DTMF
Call Ends
Thanks for your assistance!
