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

kvitug · ‎08-08-2018

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.

Do you have CUCM?

I do not. I have the sip version 8800s.

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?

kvitug · ‎08-15-2018

Correct. They register to an outbound proxy

Are you using 11.2.1 firmware?

kvitug · ‎08-16-2018

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?

bijpraka · ‎08-16-2018

A similar issue has been fixed in 11.2.1 after it was reported. Do let us know if it works for you.

Thanks.

do you have the bug ID related to this issue? Appreciate it thanks

bijpraka · ‎08-16-2018

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.

kvitug · ‎08-16-2018

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

bijpraka · ‎08-16-2018

You can send them to me at bijpraka@cisco.com

Thanks.

No further reports has been made since upgrading the firmware to 11.2.1. Thanks
