Hi,

you do first this: http://www.voip-info.org/wiki-Asterisk+Cisco+CallManager+Integration

and then you set inside of Asterisk the calling-number to those of which you want to switch on/off MWI and call through SIP-Trunk the MWI-on/off-pattern.

Hi

Thanks for your reply.

Use Asterisk, when a user bind to the IP Phone have an unread voicemail, can Asterisk call the user's extension and switch on/off MWI automaticly ?

I read the TAPI documents recently and know ITPhone interface can be used get/set lampMode. but this only works on local phone.

Acutally, my requirements are: I will write an application which will check user's voicemail, if there is any unread voice mail, the app will send Message Waiting Indicator on the user's phone. I am blocked at the place which send MWI to others phone. I mean my program will use TAPI/TSP to light other user's phone lamp(Message Waiting Indication). But from TAPI documents, IAddress Object can only get from my own phone, I can only get my ITPhone object and I can't get the ITPhone object of other user. So I can only control MY phone's lamp not others.

Does anyone have any idea on how to set other user's phone lamp using TAPI or other way (SIP?), If there is any way: I can dial a number which can light on other's phone lamp?
