[asterisk-users] Flowroute: howto set outbound callerid (ast 1.4)?

[Patrick Lists]

Hi,

The flowroute website mentions that they set callerid on outbound calls 
based on the presence of (in order of preference): 
"P-Asserted-Identity", "Remote-Party-ID" or "From:".

I've been trying to make outbound callerid work via flowroute to no 
avail. Does anyone have an extensions.conf / sip.conf snippet howto make 
this work? This is for Asterisk 1.4.44.

Thanks!
Patrick
