[christianbernal]

Good day!!

One question, I try to change the firmware to Cisco 8831 for this "cp-8831-sip.9-3-4-SR2-3PCC.bin.sgn" for connecto to other vendor PBX.

But way CUCM OS Administration --> Software Upgrades --> Install/Upgrade not is possible the firmware don´t appear in the list.

I try with url page http://<dirección_IP_del_teléfono>/upgrade?tftp://<dirección_IP_del_servidor_TFTP>/<archivo_binario_del_firmware>

http://10.118.49.41/admin/upgrade?tftp://10.127.3.73/cp-8831-sip.9-3-4-SR2-3PCC.bin.sgn

10.118.49.41 IP Address CP 8831

10.127.3.73 IP my host TFTP Server.

Firmware: cp-8831-sip.9-3-4-SR2-3PCC.bin.sgn

But show the next error:

Actually the CP 8831 have the firmware:

Active Load ID:

sip8831.10-3-1-1

How I changed the firware for CP8831 ??

Check you tftp path i believe it is not pouting correctly. Just upload any other Firmware image and see if that pop up via tftp.

Hi Christian,

My understanding here is that once an 8831 has been configured with Cisco "enterprise" (standard) firmware it can no longer be converted to use 3pcc firmware;

Upgrade from Third-Party Call Control to Enterprise Firmware

You can upgrade phones from the third-party call control firmware to the enterprise firmware.

Caution

After you upgrade to the enterprise firmware, you cannot revert to the third-party call control firmware.

In this moment the CP8831 it is registered with the CUCM,

Then it is not possible? I need a new endpoint for this?

Sadly yes, that is my understanding here my friend.

Would a hard/factory reset solve this issue?

you might try reading the following discussion:

A hard/factory reset will not solve the issue. Once the phone is locked to an Enterprise firmware it is there to stay.
