[Asterisk-Users] 7940/60 TFTP Problem

Thu Oct 9 06:25:37 MST 2003

Rich,

Thank you for your response.  I have tried to do that.  Unfortunately the oldes version of code available on the Cisco site is 3.2.  The current code rev on the phone is 3.3 MGCP.  Unfortunately I get the same results.

I start with version 3.2 - Did not work, then tried 4.4 and that did not work.  We all already know 5.3 has not been working.

Would someone have a 2.2 SIP that I could try to keep in accordance to Rich's methodology?
