m=audio 5016 RTP/AVP 96 3 107 110 0 8 101.
Is there any digits represents sip codecs in subject?!

Can any body describe this statement?!

For example in response to one of my questions, Steven told me:
"Your phone is not offering any codecs in the INVITE:
m=audio 15696 RTP/AVP 19
The only payload type listed is 19 (comfort noise) - there are no codecs listed."
