VoIP hardware is developing fast - this is where you ask all those “how do I make my SIP Telephone, Adapter or Asterisk box work with my voip provider?” questions.

Good afternoon,

I'm looking for some assistance with setting up a Cisco 8841-3PCC with Asterisk. Every reference I've seen on this forum in regards to TFTP Booting the phone refers to the classic XMLDefault.xml but this phone seems to request 8841-3PCC.xml and then it's individual config Cisco/CP-8841-3PCC/<mac>.cfg from the TFTP server. Can anyone help with generating these files or pointing me in the correct direction? Or is there something I'm fundamentally missing with this phone.

For reference:

Product Name: CP-8841-3PCC-K9
Serial: FCH2421DFFT
Software Version: sip88xx.11-2-3MSR1-1.loads

Hi @IQHQ-IT,

You have the 3PCC (3rd Party Call Control) series with Multiplatform Firmware.
(The latest version for your phone is 11.3.4 - If you want it let me know.)

Unfortunately I'm not familiar with this series and so I need to do some research on it. :nerd:

In the meantime, go through the MPP admin guides as that contains much information on the subject.

You can generate the default xml on the phone itself using the following URL:
http://[IP_ADDRESS]/admin/cfg.xml

Post that here and I will get back to you. 👍

Thanks Paul. I've been able to access the web interface and I've tried to get the device to do a firmware load over TFTP(to at least bring this up to date) but I see the following error:

I suspect though based upon your response above, the 11.7.1 firmware is too late for the phone which may account for this error. Would you be able to provide the last firmware which means the device will work on Asterisk? That might be a good place to start :)

Cheers!

Before we go any further...

Can you verify that the device has a valid factory-installed device certificate: Applications > Status> Product Info > Certificate. Scroll down to look for the message Certificate: Installed. If you do not see this, the phone cannot be provisioned for use.
