Chanspy should do exactly what you want. If you ran

exten => blah,n,ChanSpy(SIP/provider)

Then you would be able to listen to all active calls involving any channel whose 
name begins with 'SIP/provider'. If it turns out that there is a channel called 
'SIP/provider-12345abc', then that channel may be spied on with the above 
ChanSpy call in the dialplan.

The thing to remember is that the "chanprefix" argument as it is described in 
ChanSpy's documentation is literally any text that may appear at the start of a 
channel name. Chanspy(SIP) would allow you to spy on any SIP channel, whereas 
ChanSpy(S) would allow spying on both SIP and Skinny channels. There is no 
minimum or maximum limit to what this string may be.
