> So I've noticed that RTP Keepalives work just fine for audio, but they don't function for video.
> Here are the changes needed to be made for keepalive packets to function for video:
> In res/res_pjsip_sdp_rtp.c:
> Change the following (Line 2032):
> if (media_type != AST_MEDIA_TYPE_AUDIO) {
> to: if (media_type != AST_MEDIA_TYPE_AUDIO && media_type != AST_MEDIA_TYPE_VIDEO) {
> ALSO
> Change the following (Line 2061):
> if (session->endpoint->media.rtp.keepalive > 0 &&
> 			session_media->type == AST_MEDIA_TYPE_AUDIO) {
> to
> if (session->endpoint->media.rtp.keepalive > 0 &&
> 			(session_media->type == AST_MEDIA_TYPE_AUDIO || session_media->type == AST_MEDIA_TYPE_VIDEO)) {
> Sorry guys, I don't know how to make a patch... But these 2 line changes will fix dysfunctional keepalives for video.
