Dial tones not works (WaitExten)

Hi,

We have an asterisk working fine but with one problem , when some people call to the real associated number and enter one extension (in one mobile for example pressing some number) the log says :

Oct 9 02:52:33 NOTICE[26107]: rtp.c:509 ast_rtp_read: Unknown RTP codec 127 received
Oct 9 02:52:33 NOTICE[26107]: rtp.c:509 ast_rtp_read: Unknown RTP codec 127 received

and nothing happend. the extension is not dial by user.

Conf : asterisk 1.09 , debian, codecs 729 and 723 working , we can reciebe and make calls, softphones works etc etc only this issue.

Thanks and sorry my bad english
