> res_rtp_asterisk interprets the DIGITS as SSL-Traffic which is not correct.
> When testing the same situation with Asterisk 1.8.26.1 the same telephone behalfs normal - the DTMF-digits are interpreted correctly by Asterisk.
> So something seems to be wrong in the packet interpretation in Asterisk 11.
> Unfortunately I'm not able to reproduce this error in my own environment as I found it in a customer ones where I'm not able to execute phone-tests from remote.
