Hi All,
I was setting up CUBE-SIP-to-SIP trunk for PSTN. This router is also set up for SRST and it has relevant dial-peers configured. After configuring this I saw following messages trying to send the register messages to registrar:as.nipt.telstra.com. The service provider saw those message as well. To stop this initially I shut down all the dial-peers and later I had to add "no sip-register" and after no shut I can see those messages have stopped. I am now wondering why this happened? Why these dial-peers were sending the messages? Is adding "no sip-register" a solution or just a work around.
