[Freeswitch-users] CallerID withheld problem

[Alex Lake]

One thing I could do with help on is how to make the sip_cid_type work 
for INBOUND calls?

i.e. ignore what's in the P-Asserted header and just take the "from" 
address.

I don't have a specific trunk set up for these calls, they just come in 
on IP-authorised acl.

FWIW, this carrier is the only source of inbound traffic on the box, so 
setting a global default would be acceptable.

Cheers!
