No audio when webrtc mobile clients connected in different network

In my current project ,we are using webrtc to connect two mobile clients in android.
We are using socket signaling to exchange data between two mobile clients.
We were able to connect peer to peer audio and video call in android mobile clients in same and different network.
Now we changed socket signaling to verto module signalling of freeswitch so that we can make pstn call using webrtc.
After using verto module of freeswitch as signaling,we are able to make pstn call successfully.
Now when trying for peer to peer call using verto module,we are able to successfully exchange media between two verto android mobile clients.
We are able to hear audio flow between two android mobile clients when they are present in same network.
But we are not able to hear audio when two android mobile clients are in different network.
Only observation from logs is ice candidate failed in negative case scenario.
We are using same stun and turn server for app to app call in same network too.

Do you allow access to the FreeSWITCH RTP ports on your firewall? ` a=candidate:3297344421 1 udp 659136 52.53.75.119 19532 typ host generation 0` means the remote peer needs to be able to reach 52.53.75.119:19532 on your FS box. – Thurmond
solved that issue bro i was forwarding sdp without ice cadnditates to freeswitch – Edveh
Hey @Jeeva, Can you please assist in this issue? I am having the same issue, but in my case, it acts like unidirectional communication. Your assistance might help us. #69435895 – Scirrhous
@MuhammadUsmanBashir bro suggested what i did in my code hope it helps you – Edveh
Thank you so much for your assistance. @Edveh Is there any possibility that you can give me 10-15minutes on google meet, that would be really helpful for me. Thanks in advance. – Scirrhous

I was sharing my sdp to sip trunk immeditely once sdp got generated which did not contain ice candidates gathered.so i waited to 2-5 seconds and forwarded my sdp which contained sdp with ice candidates and audio started flowing. Did the same while answering the calls in verto.answer.gave 2 seconds delay to reply so i can send verto.answer with sdp which contained ice candidates gathered.
