Hi , I had some problems in the past with sip trunks, asterisk-users Digest, Vol 68, Issue 4, message 6, and had a reply (message 9) saying that It could be a dns issue.
Well today I had a problem again with sip module and it really seams a dns issue. I have an asterisk, version 1.4.26.1, that has 4 bri access and two sip trunks. I'm having internet access problems and when this happens and if one of the trunks tries to reregister its panic time!!! All the sip peers goes unreachable, trunks and phones, and the sip module "freezes", sip reload takes many many time to act. My solution is to remove the sip trunks from the configuration. But why this happens? Why If there is no dns resolution of the trunks sip module "freezes" ? This is more strange because if by some reason the internet is down but still exists dns cache all is ok. (of course sip trunks unreachable) This is supposed to be like this? There is no dns tunning for asterisk+sip? To avoid this I'm starting to think putting bind in the asterisk server and publishing there the zones of the sip trunks. (Or instead of names start using the ip's) Any comments? Regards, Luis Silva
