Cisco 8800 (8851/8861) No Dialtone / Nothing happens when pressing keys

anyone else had issues w/ Cisco 8800 series phone (8861/8851) where it's powered on, but there's no dial tone, or when you try to press any keys nothing happens. As if the phone is frozen, but if you wait a while, eventually it resumes normal behavior. Doesnt require a reboot. While the issue is present, device stays register to sip server, has layer 3 connectivity. Able to WEB access to the device. 

 

Device Model firmware: sip88xx.11-1-1MSR1-1.loads

Thanks for sending the PRTs. I gave a high level look at them and it has the same signature of the issue which has been fixed in 11.2.1. An upgrade should solve this issue.

Thanks.

Re: Cisco 8800 (8851/8861) No Dialtone / Nothing happens when pressing keys

So the phone is running 3PCC firmware and you want to enable the phone to talk to a non-Cisco Call Manager. Is this correct?

Correct. They register to an outbound proxy

Are you using 11.2.1 firmware?

Beginner

Re: Cisco 8800 (8851/8861) No Dialtone / Nothing happens when pressing keys

We have sip88xx.11-1-1MSR1-1 as the baseline firmware. But we are upgrading the reported phones to 11.2.1 individually. 

 

Was there any known related issue on sip88xx.11-1-1MSR1-1 firmware?

I can confirm if its the same issue only after looking at the logs. If you can send out a PRT with debug level set to DEBUG I can check. Also, the bug was internally found so it won't be visible externally.

Thanks.

Yes. I have two debug PRT files. Should i attach them here? or should I send them to you directly? Let me know. Thanks
