-----------------------------------------

We require additional debug to continue with triage of your issue. Please follow the instructions on the wiki [1] for how to collect debugging information from Asterisk. For expediency, where possible, attach the debug with a '.txt' file extension so that the debug will be usable for further analysis.

Thanks!

Can you attach a debug log captured during startup showing what is going on during the DNS failure?

> If on startup of asterisk DNS temporarily fails, no match entry is generated, resulting in silently dropped inbound calls later on, because pjsip retries e.g. every 60s and establishes a working connection to ISP as soon DNS is working again.
> As I detected this problem about 3 hours after starting of asterisk, I'm assuming that changes of DNS lookups later on aren't recognized, too, resulting again in silently dropped inbound calls.
> Therefore, the requirement is to always be synchronous with the IP addresses used by pjsip.
