AVAYA IP 500V2 - version 11.1.2.4 build 18, Avaya Push notification correctly configured, non errors from System Status. AVAYA Workplace ver. 3.38 installed on Iphone 14, you call the extension, the APNP wakes up the extension (from System Status you see the extensions registered from IP private address because the Iphone is connected to wifi), then the phone rings you try to answer but you can't answer because the app shows "Call error".
So how can it be possible?

Thanks

Even this error message look like a config error (wrong domain in the client settings) it is most likely that the SIP domain is not part of the server certificate's SANs (subject alternative names).

You will have to have a certificate that has the FQDN and the SIP domain as DNS entry.

Hello derfloh,

the SIP domain was part of the server certificate's SANs (subject alternative names) that I've regenerated. But anyway there was clearly a problem with the certificate SSL.

I guess it's not a push notification issue and you will be able to reproduce it with workplace app open and registered.

In this case, you should check the SIP messages.

For me it sounds like that the firewall is not able to reach the client am the time or the mobile phone's ISP is blocking something.

Do you use TLS or TCP signaling?

We have a similar issue
Are you using the Avaya SBC?
Our issue is often times the call will only ring about a half ring and cannot be answered. But subsequent calls can.
Is your issue on every call or just once in a while?

If using an ASBCE, try adding FORCE_SIP_SBC_TCP_SINGLE_PORT as a NUSN.

Indeed derfloh the push notification service is working very well. I think it's about signaling as you said.
I was using TCP signaling, instead of TLS.

Last night, I've changed to TLS singnaling but the extension 228 on app AVAYA Workplace didn't get registered, because of Login failed. Invalid domain

No, I am not using the AVAYA SBC I am using AVAYA IP 500V2 with AVAYA Spaces.
Unfortunately once in a while.

Even this error message look like a config error (wrong domain in the client settings) it is most likely that the SIP domain is not part of the server certificate's SANs (subject alternative names).

You will have to have a certificate that has the FQDN and the SIP domain as DNS entry.

I regenerated the SSL certificate from the AVAYA IPO Security Settings and then the SIP registration in TLS works!!!

I tried to check the behavior of the extension registered on the iPhone in TLS and so far everything works correctly.

Thank you very much!

Sizbut, initially there was a call error with iPhones with SIP registration in TCP which sometimes happened.

Then the signaling protocol was configured in TLS and there were registration problems due to the certificate.
