| Description: | hello, there is one problem with dynamic ip-adress if asterisk register by a provider. only at program-start and sip-reload the external-ip (i used a dyndns-name) is checked with dns. my line will disconnect after 24 hours, so that i must check this change with a script to reload the sip-module from asterisk. a simply way, to solve this problem, is a dns-query for every register-request or if the last dns-request was for more then 60 seconds. i have a dns-server on the same system to speed up dns-querys and as local dns. if asterisk make a query for every register-request, the local dns send only one query to the internet and for the liftime of the dns-entry it give answer from the cache. this make using asterisk simple if the system is connected with a dynamic ip to the internet and the systemload is less then the check with a cron-job. goodby | ||

There were some significant changes to how dns is managed and we have to see if that fixes this issue. By: Russell Bryant (russell) 2005-05-23 18:03:44 This feature is not supported in the 1.0 branch of Asterisk, but you can use the 'externhost' option in CVS HEAD, and the eventual 1.2 release branch. If you need a workaround for now, you can use a periodic sip reload, but you really should try to get a static ip. | ||
