[Freeswitch-users] Audio call get converted to video call after call is bypassed using uuid_media_3p API

Hello All , Polycom VVX 500 series phones to make audio call. After call is answered i am executing uuid_media_3p API to bypass freeswitch , at this point audio call get converted to video call. I have observed that it is happening because polycom offers video codec in response to bypass REINVITE from free switch. So it is not FS issue but i want to know if there is anyway to remove video codecs before passing them to other leg. I have tried setting absolute codec string, codec string variables before bypass but they did not help. -- Thanks, Sagar
