[Asterisk-Users] Cisco 7960 Message Light on multiple phones

[Mark Johnson]

Here is what I am attempting to do (which works well on Cisco Call 
Manger).  I have some 7960's that have multiple lines on them.  The 
second line specifically is a "helpdesk" line that is shared among 
multiple phones.  Here is how I am making that line ring on multiple 
phones, maybe you have other suggestions:

exten => 135,1,Dial(SIP/135 at 100&SIP/135 at 101,20,rt)

So this rings the second line on the phones that have the first line as 
100 and 101.  This works great.  When someone leaves a voicemail, the 
messagelight will only light on the phone that was booted up last.  Is 
there a way to make the light come on all of the helpdesk phones, with 
the second line icon displaying the correct mail icon?  Here is the 
sip.conf section for those particular extensions:

[100]
type=friend
username=100
secret=100
host=dynamic
mailbox=100
linelabel="First Last"
line => 102

[135]
type=friend
username=135
secret=135
host=dynamic
mailbox=135
linelabel="HelpDesk"
line => 135

[101]
type=friend
username=101
secret=101
host=dynamic
mailbox=101
linelabel="First1 Last1"
callerid="First1 Last1" <101>
line => 101
