Voice Notification "Agent: cannot send rtp packet"

Ignition
1

I finished setting up a voice notification profile and a Grandstream HT813 using the guidelines published by IA. I used the Test Pipeline feature on the gateway config page to test it. The gateway has two NICs and I did have to set the Local Bind Address to the IP address of the NIC I have connected to the HT813 in order to get this far.

I was able to get the notification to ring my phone, but as soon as I answer, the log file starts rapidly recording errors "cannot send rtp packet" and there is no audio. When I hang up, those errors stop and I get one more error "PhoneCall: Error executing call".

In the final error, there is text telling me that "because 'sipMessage' is null". Does that mean the pipeline had no text to send to the notification block?

Attaching a screenshot of the log with two of them expanded.

What should I try next?

Thanks

Hello @OkiePC

How did you solve this? I am having the same problem

Thanks!

Not yet. I have been working with tech support on it, but we have so many other jobs going on, that I haven't had the chance to spend enough time on it to complete the tests they asked of me. When we get it resolved, I will update this thread.

I just solved the problem in my side:

1- Firewall was blocking 5060 communications. Enabling it permited stablishing the call, but no voice was heared.
2- Public bind IP address did not match neither with our real public bind address and the whitelisted IP adresses.

Fixing both solved the problem.
