drachtio config and rtpengine config | both are running in the same server and when I start to run this program getting error. ERROR, I know this is related to the port issue but I want to know how to solve it because when I change the port in rtpengine and start the service and then run this program it always gives me the same error.
drachtio-rtpengine-webrtcproxy config file

{
  "drachtio": {
    "host": "127.0.0.1",
    "port": 9022,
    "secret": "cymru"
  }, 
  "rtpengine": {
    "host": "127.0.0.1",

The problem is you moved rtpengine to listen for traffic on port 2223 instead of its default port 22222:

listen-ng = 127.0.0.1:2223

You then configured your node.js application to also try to listen on that same port, which of course fails.

Leave your drachtio config file unchanged, and modify your rtpengine config to listen for ng traffic on port 2222. Again this is the default, and you caused your problems by changing this unnecessarily.

[awadheshkumarconsta]

Thanks for your feedback.
After moving the ng traffic on 2222, Good to see it's working.
Now I'm facing another issue when I make a call which comes like

{"level":30,"time":1590591154502,"msg":"Error connecting call: Error: failed allocating endpoint from rtpengine: {\"result\":\"error\",\"error-reason\":\"Ran out of ports\"}","pid":11761,"hostname":"ip-172-31-38-128","v":1}

[davehorton]

rtpengine is saying it ran out of ports, which is strange since it is configured to have a range of 10,000 ports. Look in /var/log/syslog for more logging from rtpengine to see if you can figure out why. Also try restarting rtpengine and running your tests again

[awadheshkumarconsta]

As you told I did the same, now “ran out of the port issue is solved”, restart the rtpengine, and tried to call. It seems like the call is going but I haven’t rec. any call.

turn drachtio server log level to debug, run the node.js app with DEBUG=drachtio:* and re-do your test. Seems like some bit of configuration between the app and the server is off

[awadheshkumarconsta]

Thank you for responding!
I run the node app as you said and I've gathered some logs:
some of log lines from drachtio log, Can this be causing the issue?

Your problem is with your rtpengine config. Specifically this

interface = 34.200.127.219

I can see from the drachtio logs that that address is not a local address on the server. So then, rtpengine has no ports and gives an error:

rtpengine[940]: ERR: [kjee9g4d8oigfhbt84ed]: Failed to get 2 consecutive ports on interface 34.200.127.219 for media relay (last error: Cannot assign requested address)

That address is a public address assigned to the VM, but is not explictly bound to an interface. Change your rtpengine config to this and it will probably work

interface = 172.31.38.128!34.200.127.219

[awadheshkumarconsta]

Hi Dave and thanks for responding.
Now outgoing calls are working but I can't hear the one-sided voice in my sip client. eg- A->B is working but B->A voice is not coming. As well as When I make a call to my SIP client, the call can't come in my SIP client.

This is this log file of drachtio.
drachtio.log

[davehorton]

you should get a network trace and study it to see if you are receiving RTP on the B leg

[awadheshkumarconsta]

Hi Dave, I have checked, I think we haven't rec the RTP.

and also in drachtio log I have noticed some lines--
These types of things are common or not? basically server automatically sends invite request eg.sip:4001@34.200.127.219 which is not by my side (without using any SIP client) and gives Not Found error.

Is this the reason behind it? I haven't heard the one side voice or not rec. incoming call in SIP client?

[awadheshkumarconsta]

Hi Dave,
I have also checked in homer statistics/log and I observed "SUBSCRIBE" is also not initiate by SIP client to server. as I can see still the same error log in drachtio.

Is this the issue to making the call? Like I can not make a call to SIP client after registration (incoming call).
