Out internet connection was out this morning. It seems that the SIP extensions on our LAN were affected. Behavior like:
Call comes in over POTS to a TDM400P, there is a delay then before the Cisco 79[46]0's start to ring. If we were lucky enough to get a call through, then we could not transfer the call, or place the call on hold, or park the call. Outbound calls seemed to have a delay between the time they were dialed at the SIP phone and when they were connected. I know this has been brought up before, in fact there is a bit of a discussion going on now about DNS SRV (in sip.conf, set srvlookup=no, or put all the phone ip's on /etc/hosts). But what is really causing the issue here? Yes, it is DNS, or something related to DNS, but why does that have anything to do with * trying to make a phone ring on the LAN? I would think that by using qualify=yes for any outbound voip trunks we avoid an issue of trying to call out is the net is down, but why are any operations on the LAN affected? Sincerely, Brent A.
