Re: Connecting Cisco 7940 IP Phone to Asteriks

Have got the following from Cisco site:

OS79XX.TXT

P0S3-08-2-00.loads

P0S3-08-2-00.sb2

P003-08-2-00.bin

P003-08-2-00.sbn

The converting process states that I need 4 files namely:

SIPDefaultGeneric.cnf

SIPConfigGeneric.cnf

RINGLIST.DAT

ringer1.pcm

Cisco wont allow me to download these files. Is there any other place I can get it. Here is the details of my current 4940 IP phone

MAC Address 001BD52C578B

Host Name SEP001BD52C578B

Phone DN 5299

App Load ID P0030301MFG2

Boot Load ID PC0303010200

Version 3.1(MF.G2)

Thanks for your help

Hi,

I don't think these files are needed for firmware conversion, ignore them or supply empty ones. Later on, you can configure them for further personalization.

The firmware files only.

Manage to change that. On Firmware status it now says

Application Load ID

P0S30203

Boot Load ID

PC030301

My Asteriks box IP is 192.168.0.48and my number is 4002 with my password 2004

Thanks for your help

Re: Connecting Cisco 7940 IP Phone to Asteriks

How do I reset all the configuration of this phone to the factory default settings ?

Re: Connecting Cisco 7940 IP Phone to Asteriks

Power one while pressing #. Release when display "reset sequence dtected". Press 12345689*0#. Press again 2 to confirm network settings erase.

This will erase also the firmware, so you must have DHCP and TFTP server correctly configured to provide firmware again to the phone.

Hope this helps, please rate post if it does!

Did try that and didnt get that message "reset sequence dtected". Did recycle the power while pressing #. IT go straing into configuring VLAN and then configuring IP then back to the normal phone display

I've heard someone else with the same problem. I don't know what to say. This is only known reset sequence, it has always worked for me:
