I'm trying to set the caller id number for an outbound call.

My asterisk .call file looks like this:

Channel: SIP/flowroute/1234567890
Context: test
Extension: 1234567890
Priority: 1

Here's my extensions.conf:

[test]
exten => _1NXXXXXXXXX,1,Set(CALLERID(num)=8005552222)
exten => _1NXXXXXXXXX,n,Dial(SIP/${EXTEN}@flowroute)
exten => _1NXXXXXXXXX,n,Playback(hello-world)

When I receive the call, the caller id number is 1-206-445-6979, even though the CDR log has both src and clid set to 8005552222. I'm using flowroute as my carrier. Is there something wrong on their side?
