hi! i have linksys spa921 ip phone device connected to 3cx with bind to media server option enabled. the only codec i can use is g711. when i try to use another codec the call is established but right after the called party answers it turns down. in logs i see messages that no rtp packets were recieved and no codecs intersection found. as far as i understand when i set bind to media server option 3cx becomes a media proxy for my phone. in other words all rtp packets are first sent to 3cx and then it sends it to the other party. so seems that 3cx media proxy component doesn't support any other codecs then 711. am i right?
