attached the necessary AGI file and a screenshot of phone display.

I'm running this on Asterisk 13.13-cert3 with latest version of phpagi libs: http://phpagi.sourceforge.net/
In these libs the config file has to be edited to your needs.

Process is to click BLF key on phone while the monitored extension is ringing.
A call goes out to Asterisk where the AGI script is called.
A XML message is sent to the phone by the AGI script and the call will hang up.
On the phone you can see the caller information and pick the call.

My dialplan:
Quote:exten => _*8XXX,1,Set(VIATMP=${CUT(SIP_HEADER(VIA), ,2)})
exten => _*8XXX,n,Set(IPADDR=${CUT(VIATMP,:,1)})
exten => _*8XXX,n,AGI(pushBlfCid.php,${IPADDR},${EXTEN:2})
exten => _*8XXX,n,Answer()
exten => _*8XXX,n,Hangup(16)
exten => _*88XXX,1,Pickup(${EXTEN:3}@PICKUPMARK)
exten => _*88XXX,2,Hangup(16)

Hope this will help.

AGI of course could be edited to fit needs of other phones.
Code is surely improveable Wink

Nice job! We are trying to resolve the same problem on 4xG/4xS phones with PJSIP and still not successful. We got all VIATMP and IPADDR from PJSIP header but get immediate hangup and do not see the caller ID on BLF
