Asterisk SIP DTMF

what should be in the info message when sending Asterisk "*" or "10"?

it seems that some phones come with default as in-band DTMF, and this does not work with Asterisk' voicemail system. The question is covered in: Asterisk sip dtmfmode

Grandstream phones seem to come with in-band DTMF, which will work if you have ulaw enabled. Cisco phones also seem to come this way.
