Hello. I’m having no sound issue with Zoiper soft phone on IOS. It uses proxy to allow incoming calls to IOS and registration is coming from outside of firewall.
Everything works if I add that external proxy address as localnet. If I don’t, it registers and I can call from it and it rings as extension but has no sound. And while it works with localnet, I wonder if my set up is correct.
I’ve tried multiple values for sip setup:
I have port 5060 forwarded. Without which it cannot register.
Forwarding RTP 10k-20k doesn’t make any difference.
Is having it in localnet the only way to fix it? Or am I missing something?
Asterisk version is 16.2.1
