Have you seen the following?
http://www.voip-info.org/wiki/index.php?page=Asterisk+phone+cisco+79xx
It contains a guide on how you can use ALERT_INFO to set the ringtone.

Another method would that might work would be to configure two lines on the phone and have each one connect to asterisk using a different account with a different ringtone assigned to each. Then if a call comes in on your home phone you can call line2 instead. Thats what I do with my home system.

I originally wanted to do your second solution.  But everything I read says I cannot specifiy a ringtone. for different lines How would I specify this???  Using the conf files in the TFTP server???  Any help on how you accomplished this would be great.

If you cannot set a different ring per line on the cisco then you will need to use the alert_info method.

You said you got it working though correct?  How did you set it to use different ring tones for different lines?

No I have a Grandstream GXP-2000 phone not a Cisco one.

Have a look at the URL I gave earlier and scroll down to the section titled 'Controlling ring tones from Asterisk'. That may help you.

Thats what I was trying to do previously, but im a little lost by what SIP_Head is in version 1+  can you clarify this?

The documentation is a bit poor in that regard. Basically :-

If you are running asterisk 1.0 or 1.2 you need to use something like :-
exten => 3010,1,SetVar(_ALERT_INFO=Bellcore-dr1)

But if you are running asterisk 1.4 you need to do this instead:-
exten => 3010,1,SIPAddHeader(Alert-Info: <Bellcore-dr1>)

I have modified the wiki entry to make it easier for people to understand.

Tried your hint for an Asterisk / Trixbox 1.2..  An did a Reload after saving the change..

Attempting to get two different rings for 2112 VS 2312 riinging on the same phone..

Would Also like to vary Internal VS outside.  

extensions_additional.conf
[ext-local]
include => ext-local-custom
exten => 2112,1,Macro(exten-vm,novm,2112)
exten => 2112,2,SetVar(_ALERT_INFO=<Bellcore-dr3>)
exten => 2112,n,Hangup
exten => 2112,hint,SIP/2112
 
Did I miss something here ??  Can this be done thru FreePBX ?

TIA,  JMS

The macro will dial the extension so you will need to make sure the variable it set before that. For example :-

exten => 2112,1,SetVar(_ALERT_INFO=<Bellcore-dr3>)
exten => 2112,n,Macro(exten-vm,novm,2112)
exten => 2112,n,Hangup
exten => 2112,hint,SIP/2112

:-(  Still only getting the standard Chirp --
      Phones are P0S3-06-3-00.bin  
   
      Guess I will hold on this till I get a chanceto do updates latter this month.

      Thanks,
       JMS...

Okay, I will try it again over the weekend.  Some of the reading I have been doing indicates that the change only impacts the cadence of the ring, and not the ring specifically.  To do what I would like to accomplish I apparently need at 7970 phone.  

JMS...

This is an extremely old topic, but it helped me out on an extremely old 7960.

If anyone ever actually revisits this, from the info at http://www.voip-info.org/wiki/index.php?page=Asterisk+phone+cisco+79xx I can only get the bellcore-dr tones to ring--and all it does is change the behavior of chirp 1. "Latest" SIP firmware (003-8-12-00) running asterisk1.8. As Noodles noted, you can put it in FreePBX where the Alert-Info field is, such as inbound route, ring group, or the extension itself.

I have another program (a HUD) triggering calls, so I had to setup a dial plan in extension_additional.conf

like this:

[from-internal-custom]
;# // Reduce ringtone time on 7960
exten => 1201,1,SIPAddHeader(Alert-Info: <Bellcore-dr5>)
exten => 1201,2,Page(SIP/1101)
exten => 1201,3,Hangup

The 1201 above is the "extension" to be rung (from any endpoint you can ring 1201 and it will trigger this dial plan). It adds the header for Alert-Info, then the second line calls the actual extension (1101), then hangs up the fake extension (1201), since it has passed the call on to the real extension already.

Hope this helps anyone, though I doubt it ever will.
