One way Audio when I accepted incoming call with Video Option

Hi,

I am having a similar issue with the person in this post, but i didn’t found a solution in it:

There is no problem about audio call, issue occur when i tried to make video call.
Whenever i try to make a video call, no matter it is outbound or inbound, There is always one way audio.
Scenario like this:

Device 1 -> Device 2:
Device 2 have both video and audio streaming ; Device 1 only has video streaming but no audio streaming

Device 2 -> Device 1:
Device 2 still have both video and audio streaming ; Device 1 still only has video streaming but no audio streaming

Device 1: Mac with Linphone 3.10.2
Device 2: Iphone5 with LinphoneSDK App

I am using chan_pjsip with asterisk 13

following are my pjsip.conf

[transport-udp]
type=transport
protocol=udp
bind=0.0.0.0

;Templates for the necessary config sections

Please provide a SIP trace as well so we can confirm that it is negotiating properly. This can be done using the “pjsip set logger on” CLI command.

Following are my SIP tracks, from my observation, there should be no
problem:

<— Received SIP request (973 bytes) from UDP:124.82.88.231:5060 —>
