Logs will show you the problem. You may need to enable sip debug also.

Be sure to enable NAT in your Asterisk SIP settings and extension configurations. And set the correct external IP address.

702 is not offering video in the invite.

 

[bend94]

tell me what parameter do i have to set for 702 ?

 

[billsimon]

It means you are starting the call from zoiper as an audio only call. You need to start the call as a video call.

Hi
Thanks for your reply.
It is strange because i started a video call from zoiper.
I noticed that when i called from one side let say from 702 (from internet) to 703 (at home) first i have voice then i clicked on incoming and outgoing video it is working voice and video.
But if i called from 703 (from home) to 702 (internet side) even when i clicked on incoming or outgoing video i can t get video but only voice.
What do you think?
Thx

Am I correct in assuming vp8 is the only video codec being offered? Do both endpoints support vp8? What about enabling other codecs for video?
