> Since adding [all remaining rates|https://issues.asterisk.org/jira/browse/ASTERISK-24274] of Signed Linear (Asterisk 14.0) and [SILK|https://gerrit.asterisk.org/3136] (Asterisk 13.11), only one [RTP Payload Type|http://www.iana.org/assignments/rtp-parameters/rtp-parameters.xhtml#rtp-parameters-1] in the dynamic range (96-127) is left. That is going to be taken by [Codec 2|https://issues.asterisk.org/jira/browse/ASTERISK-26217]. One approach would be to assign only those types which are allowed in {{/etc/asterisk/sip.conf}} (or {{pjsip.conf}}). However for example, when all codecs are allowed, the issue persists.
> [RFC 3551 section 3|https://tools.ietf.org/html/rfc3551#section-3] offers an alternative: ‘\[…\] applications which need to define more than 32 dynamic payload types MAY bind codes below 96, in which case it is RECOMMENDED that unassigned payload type numbers be used first.’
> The attached patch fixes this issue giving room for at least another 54 RTP Payload Types.
