One way audio with PJSIP [on VPN]

1bsilver · October 19, 2023, 12:27pm

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 call is place. But I cannot hear anything on soft phone.
I am using a webrtc based softphone.

Here are my RTP logs.

Got  RTP packet from    106.*.*.*:49556 (type 00, seq 020561, ts 3373454619, len 000170)
Sent RTP packet to      192.168.250.123:8000 (type 00, seq 029894, ts 3373454616, len 000160)
Got  RTP packet from    106.*.*.*:49556 (type 00, seq 020562, ts 3373454779, len 000170)

Got  RTP packet from    106.*.*.*:49556 (type 00, seq 020563, ts 3373454939, len 000170)
Sent RTP packet to      192.168.250.123:8000 (type 00, seq 029896, ts 3373454936, len 000160)
Got  RTP packet from    106.*.*.*:49556 (type 00, seq 020564, ts 3373455099, len 000170)
Sent RTP packet to      192.168.250.123:8000 (type 00, seq 029897, ts 3373455096, len 000160)

I am really stuck. Would appreciate any kind of help.

Have you configured Asterisk to know it is behind an AWS NAT environment in rtp.conf and pjsip.conf? What is the actual SIP traffic (pjsip set logger on) and corresponding IPs?

You’ve configured the transport so it has no knowledge of local networks, it is putting the EC2 public IP address in the SDP for where the remote side should send audio. You would need to set the local_net[1][2] appropriately such that the IP address remains the local one.

[1] https://github.com/asterisk/asterisk/blob/master/configs/samples/pjsip.conf.sample#L1086
[2] https://github.com/asterisk/asterisk/blob/master/configs/samples/pjsip.conf.sample#L139

1bsilver · October 19, 2023, 1:02pm

Do I need two local_net definitions?
And should I put the EC2 public IP address in the local net?
And what would be the other local_net address?

1bsilver · October 19, 2023, 1:04pm

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

jcolp · October 19, 2023, 1:05pm

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 your local networks are.

1bsilver · October 19, 2023, 1:08pm

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.

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

1bsilver · October 19, 2023, 1:16pm

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.

jcolp · October 19, 2023, 1:18pm

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.

1bsilver · October 19, 2023, 1:19pm

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

jcolp · October 19, 2023, 1:19pm

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

1bsilver · October 19, 2023, 1:30pm

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 wireguard.
This network actually exists on other local machine which connected to the gateway through ethernet.

Here are my sip logs.

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.

1bsilver · October 19, 2023, 1:36pm

My network is like this.
EC2 → VPN server [10.5.5.1] → VPN client [10.5.5.2]
10.5.5.2 is another linux machine connected to the GSM gateway via ethernet [192.168.250.123]
And now I am able to ping 192.168.250.123 from my EC2 because it is connected to the VPN client.

jcolp · October 19, 2023, 1:38pm

I’m not really sure what you want me to do with that information.

1bsilver · October 19, 2023, 1:40pm

This is my ip route on my EC2. Maybe that’s why dinstar is responding with 480 Unavailable.

ip route on my EC2
default via 10.0.0.1 dev eth0 proto dhcp src 10.0.0.32 metric 100
10.0.0.0/24 dev eth0 proto kernel scope link src 10.0.0.32 metric 100
10.0.0.1 dev eth0 proto dhcp scope link src 10.0.0.32 metric 100

10.5.5.0/24 dev wg0 proto kernel scope link src 10.5.5.1
192.168.250.0/24 dev wg0 scope link```

This is my IP route on my local machine [VPN client]

192.168.250.0/23 dev wlxa42a9545e661 proto kernel scope link src 192.168.251.9 metric 600

I have added these commands on my VPN client to forward the requests to my VPN server
