<p class="MsoNormal">If a call is made from a phone that does not include a video codec (i.e. H.264), Freeswitch still offers H.264 as a codec in the INVITE to the callee. I think this is because H.264 is included in the inbound-codec-prefs and outbound-codec-prefs
of the sip_profile (which is needed to support video calls).<br>
<br>
Is there an easy way to configure Freeswitch to exclude H.264 based on the caller's INVITE? Because it never would make sense for it to offer H.264 in this scenario.<br>
