I have seen this before if you are using PFSense as your outbound router and you are NOT static locking NAT outbound, it will pick a port at random.  Other firewalls have also done it if not set for static, but most consumer grade routers do NOT mangle NAT this way.

    Ok, are you behind NAT?  What are you doing there that iax is not connecting
    outbound with a source port of 44569?
    
    I just pulled a dump of your traffic to the registration server and I see
    you're hitting it with a source port of 54799, not 44569.  I think this has to
    be some nat funkyness, using a different outgoing port vs incoming.
    
    Can you check that and give some details if you are behind nat as to the setup
    you have?
    
    Thanks,
