Is there a way to blacklist a CNAME? I’m not opposed to writing code. The problem is harassing calls coming from a different CID every time, but the CNAME is always the same.
I get my CNAME on the call like this:
INVITE sip:[email protected]:53485 SIP/2.0
Via: SIP/2.0/UDP 64.0.0.0:5060;branch=z9hG4bK3009f0fe;rport
