Multiple sip accounts per phone

hello, I need to configure an AAStra 480i CT to run 2 sip accounts simultaneously. One account is for the general office and one is for the receptionist directly. I need both to ring in to the same phone with hopefully some type of distinguising message/ring so she knows if the call is for the office or for her directly.

Is this possible?

For that just add this line b4 ur dial command

SIPAddHeader(Alert-Info: )
now here cisco-beepBonk is cisco ip phoen pattern for Astra may be diffrent actually some thing like distuctive ring
So make to such sipaddheader for that 2 line & njoy
