Help Setting up a Cisco 7942 VOIP Phone

NightHawk099 · Mar 18, 2017

Hi

I need your help to get a Cisco VOIP flashed. I am new to VOIP in general, so I am really struggling, but have checked out a lot of information and websites on how to do this. I am on the right path. However, it seems I am missing something and are stuck...

Here is what I have done so far:

I have downloaded the SIP firmware for the phone, unzipped it and placed it in a folder.
I am have reset the phone using the 789456123*0# method
I have created a XMLDefault.cnf configuration file for the phone, and placed it in the same directory as the firmware.

I dont have access to Cisco comunication manager, so I am doing TFTP. I have contected the phone directly to my computer (no router or anything). So I am manually asigning the ip address 192.168.2.100 to my PC, with subnet 255.255.255.0. Using Tftp64 I have created a DHCP server on my computer, with option 150 pointing to the PC address (192.168.2.100) as well as a TFTP server lisening on the same address. The phone is pinging the PC, and gets an address assigned by DHCP as reported in the log and Tftp64... however nothing else happens. THere seems to be some comunication between the phone and PC, but it seems to be repetitive, dont know enought about networks to know what its going on. I am not sure what to do next or what could be going wrong

Here is the log from Tftp64. 0C:85:25:A6:2F:96 is the MAC address of the phone.
