Hi, nathelper generates a keepalice request with
branch=0:
OPTIONS sip:9.9.9.9:12345 SIP/2.0
Via: SIP/2.0/UDP 1.2.3.4:5060;branch=0
From: sip:nat_keepalive@mydomain.org;tag=b240e8a7
To: sip:9.9.9.9:12345
Call-ID: 786219c2-7c0b783-2d(a)1.2.3.4
CSeq: 1 OPTIONS
Content-Length: 0
Why not to use a SIP/2.0 compliant branch (z9hG4bK...)? any reason?
Maybe this is the method to detect keep-alive replies and absorb them
before they enter dialplan processing.
