[Asterisk-Users] turning off IAX registration attempts
I have, in iax.conf the register statement:
register => username:password@iaxtel.com
This causes registration attempts to iaxtel.com for both IAX and IAX2.
Every once in a while there is a packet for port 4569 keeping the IAX2
registration alive. This is fine.
But, I have a barrage of registration attempts to iaxtel on port 5036 for
IAX. Every UDP packet is answered with an ICMP packet claiming
"port unreachable".
I know that iaxtel has turned off IAX, So, how do I turn off the registration
attempts for IAX, for that particular connection? (and keep IAX2)
Just seems like alot of wasted bandwidth, contiously knocking on a locked door.
Ok, not alot of bandwidth, but, completely useless.
Has anyone done a tcpdump at iaxtel to see how many IAX registration attempts
hit them, and how fast?
Here is my tcpdump: there are ICMP return packets for each of these UDP packets
root@hiro:/etc/asterisk# tcpdump -n ip host 69.73.19.178 and udp port 5036
tcpdump: listening on eth0
