I have an Asterisk server on an AWS EC2 Machine. I have another linux machine connected to a GSM Gateway. I connected my EC2 machine with my local machine using Wireguard VPN. I am able to make calls from my Asterisk server through the GSM gateway via the VPN. I can hear audio on my phone when a…

Also should I define another block as such: ; UDP transport behind NAT ; ;[transport-udp-nat] ;type=transport ;protocol=udp ;bind=0.0.0.0 ;local_net=192.0.2.0/24 ;external_media_address=203.0.113.1 ;external_signaling_address=203.0.113.1

You don’t need another transport. The local_net option specifies the local networks, not the public IP address. For example: local_net=172.16.1.0/24 If a SIP request is sent to that network, then no substitution occurs and the public IP address would not be put in the SDP. I can’t tell you what y…

These are my local networks. I am using wireguard VPN on 10.5.5.1 My vpn client is connected to 10.5.5.2 through which my gateway is connected on 192.168.250.123 I have tried setting the local_net as 10.0.0.0/24 and 10.5.5.0/24 but I was facing the same issue. ifconfig eth0: flags=4163<UP,BROAD…

Did you reload things after changing configuration? And if so, provide a new SIP trace and new configuration.

Yes I did reload. Here is the new sip trace after setting the local_net=10.5.5.0/24 Still cannot hear the audio on one side. <--- Received SIP request (7776 bytes) from WSS:106.*.*.*:49720 ---> INVITE sip:123456789@asterisk-serv.ec2.com SIP/2.0 Route: <sip:asterisk-serv.ec2.com:8089;transport=ws;…

[image] 1bsilver: 192.168.250.123 This is the IP in use with the dinstar from what I can tell, which is not within the local_net configured and thus is using the external IP address.

Yes you are right. Should I try configuring local_net=192.168.250.0/24

If that is the network range that it is in, yes.

I tried setting local_net=192.168.250.0/24 But it didn’t work. Now I am not even able to connect the call. I get ringing but it ends the call as soon as I pick it up sometimes even before that. 192.168.250.123 is what dinstar my gateway is on. I am able to ping it from my ec2 machine through wi…

[image] 1bsilver: 10.5.5.1 The SDP now contains this IP address. The dinstar is responding “480 Temporarily not available”. I have no insight into why it is doing that.

Solved it.
The problem was my LAN ip.
The LAN IP I assigned was not the gateway of my GSM box.
Thanks everyone who tried to help me.
