[Freeswitch-users] Is there a way I could separate by destination types by hardcoding it in?

[D-Roy Black]

Normally calls coming in from the PSTN to an unprovisioned telephone 
number are given session:hangup("UNALLOCATED_NUMBER");

Now I have a setup like this, that any call coming in from the PSTN to 
an unprovisioned telephone number is sent to an IP address, and works 
fine...
session:execute('bridge', 
'sofia/internal/gateway/'..dialledNumber..'@100.100.100.100:5061');

But is there a way I could separate by destination types by hardcoding 
it in?
i.e if a caller dialing to 0800 or 0208 UK

(sofia/internal/gateway/44800
(sofia/internal/gateway/44208

Any number beginning 44800 should go to 
session:hangup("UNALLOCATED_NUMBER");

And anything ells would go to the IP address
session:execute('bridge', 
'sofia/internal/gateway/'..dialledNumber..'@100.100.100.100:5061');

Thanks :)
