Doro Sip Phone Issues

HI All,

I have a doro sip phone which registers fine to the system but when I try to dial an extension or number it says the following:

Not Acceptable Here any ideas?

Thanks

Mike

Not Acceptable Here generally means that the codec configuration in Asterisk does not match that of the phone. What is the configuration in Asterisk and what is the console output with sip debug turned on? (If using PJSIP then pjsip set logger on - if using chan_sip then sip set debug on)
