[asterisk-dev] Rouge ipv4 registration requests

[Roger James]

I am looking into the generation of unwanted ipv4 registration requests 
when registration is configured for ipv6 only.

[AAPJSIP]
type=registration
transport=ipv6-udp
outbound_auth=AAPJSIP
retry_interval=60
fatal_retry_interval=30
forbidden_retry_interval=30
max_retries=10000
expiration=3600
auth_rejection_permanent=no
line=no
server_uri=sip:voiceless.aa.net.uk
client_uri=sip:xxxxxxxxxxx at voiceless.aa.net.uk

I am struggling to find a good place to put a breakpoint at the start of 
the registration process for this transport. Anyone got any suggestions.
