I'm not exactly sure what it is you're asking but if it's whether or not to call his all in then I say but of course. However, I've had this similar scenerio and found that the person jumping all in had slow played his pckt. pair and I ended up out on my arse. 

Hey, thanks for the nice welcome everyone. Ya'll know how to make a gal feel all schmooz ;thankyou;y ...

Oh Happy Day... la la la la la la

 

Wow thanks for the warm welcome... oh and btw,....all this time I wondered about the end.... is it really tight? ... we'll just have to reserve judgement for a later time.
