Skype and bluetooth problems

[neil4374]

I am having difficulty using bluetooth headphones with skype and the ipad 2.
After calling from skype and using bluetooth headphones and mic once, the bluetooth headphones will not work again and switches to the ipads speaker.

The headphones are Plantronics backbeat 903+ headphones.

I.o.s is 5.0.1 (ipad2)

and skype is 3.6.97
