FreePBX in Amazon EC2 cloud, and SipStation Trunk issues!

On another note, the second post here: SIP Trunks are de-registering up to 4 times a day!
makes it sound like asterisk only tries to register 10 times and then stops. Does anyone know if that’s still the case?

If so, would setting registerattempts=0 as per the post above potentially be helpful?

Thanks!
