Cisco 8841 Phone registration to Asterisk Server

[mohdshajan]

Hi all,

I am trying to understand the process of registering a normal Cisco 8841 phone (non-MPP) to an Asterisk server. Do we need to change the current and default SIP load firmware to make it work or we just need to only upload the .cnf file with Asterisk server details to the phone via a TFTP server?  

Appreciate your support. Also, is it better to consider 3PCC phones for future Asterisk deployments ?

Regards

For simplistic sake, yes.

You will need the following: 

1. A known working SEPmacaddress.cnf.xml file; 
2. A known working dial plan file; 
3. Firmware firmware of the phone; 
4. DHCP Option 150; and 
5. A TFTP server will all the files found in #1, #2 and #3.

Hi Leo,

Can you guide on the item 2 and 3 ?Which firmware we need as the phone is already on SIP ? Also, is the dial plan info not taken from asterisk server?

Paste the following into a text file and call it "dialplan.xml"

<DIALTEMPLATE>
 <TEMPLATE MATCH=”*” Timeout=”5″ User=”Phone” />
</DIALTEMPLATE>

Above instructs the phone to "wait for 5 seconds before dialing the number".

Whatever version you want.  CP-8841 only operates in SIP.
