[Asterisk-Users] cisco 7960 SIP setup

[mk111]

I can't get the 7960 to reconfigure and work. I am a newbie to voip. I 
went through the list and read some other comments about the 7960 and 
unlocking it. It is a used 7960 that came with CallManager. I need to 
have SIP. I first reset the phone to factory defaults then I changed 
the TFTP server address in the settings. I have unlocked the phone with 
**# and it shows the lock as unlocked in the upper right hand corner. I 
was told that the phone should be able to download the SIP... file once 
the TFTP address was changed. So far nothing though. Any ideas?
