Don't know what you mean by "that does not suit me"
Simply create a file with no contents and the load will be happy
There is plenty of information available on how to up the 7960 from SCCP 
to SIP, and I assume from your question you are in the transition from 6 
to 7.
Use Google, look on the voip-info site and you will find step by step 
procedures.
Different versions of now obsolete firmware are also on the Net.
7961, 7970 results may vary!

You need to work your way up, version by version as well.

The problem I now have is version 7.1 works fine, version 7.3 won't 
place any calls and goes to reorder.  Asterisk shows it trying to go to 
a non existent context, not specified in sip.conf

Any ideas?
