Cisco ATA 192 Not Receiving another call after one inbound call

jzeglin — Wed, 03 Jan 2024 13:06:13 GMT

Hope someone can help.

We have followed the setup instructions for the ATA192, we can make outbound calls with no issues. We can receive 1 call, but cannot receive another call for around 10-15 minutes. The line goes straight to voicemail, the line status on the ATA GUI page is showing the line is not active. It just seems it is not sending the disconnect message on incoming calls telling RingCentral the incoming call is complete. We can make an outbound call and receive a call afterwards, which is the strange issue.

I've also found these errors in the logs, I believe it has something to do with the BYE message:

ATA192-MPP local1.err vsock: RTP_LIB: librtp_wait_for_rtcpbyemsg():548: librtp_wait_for_rtcpbyemsg Failed to recv RTCP BYE from CSS and time out happened

Hi,

Are you using the ATA with MPP software or CUCM registered?

Please let me know

Not using either. Just have analog phones connected to the ATA.

In some way , you need to connect it to a call control system such as CUCM or Sip Proxy.

How did you configured it?

I currently use RingCentral. They gave me SIP credentials to enter in. It shows it is connected on their end, making calls is no problem. It is connected to their SIP proxy with the details they've provided me.

So the answer is, you are using a 3PCC or MPP firmware.

Please change SIP Transport to UDP and retry.

Thanks

Changing to UDP gives registration failures. They require TCP or TLS.

Can you send me some screenshot of your config?

Thanks

I figured out the issue. It has to do something with RingCentral's call waiting option. I have it turned off on their portal and the option deselected in the ATA. I turned it back on in their portal and now calls are able to go through back to back.

I don't know why this is causing much of a hiccup in the system, I may have to call them about it.
