[asterisk-users] Re: Cisco 7970 MWI not working (Was: Problem withCisco7970 SIP load / call transfer)

[Michael J. Tubby G8TIC]

Forgot to say running with Asterisk 1.2.10 mainline code on RedHat FC5 box. 
Other Cisco 7960 (SIP 7.5) and 7912 phones (SIP ver 1.3.1?) around the house 
work as expected including MWI...
