I am trying to connect an incoming call to freeswitch using speech wideband, but freeswitch is returning a 488 Not Acceptable here. It seems like freeswitch, which is using dynamic payload 99 for speex is unable to match that up to the fact that the remote side (client) is using payload 84. If so, this would seem to be a bug. Relevant log snippets / details: 1. Freeswitch version FreeSWITCH Version 1.6.9+git~20160613T181044Z~d574870720~64bit (git d574870 2016-06-13 18:10:44Z 64bit) 2. speex seems to be enabled...
