Re: Google DNS versus ours
Hello TSI Gabe,
Could you please tell if TSI DNS servers properly respond to DNS SRV queries as needed for correct SIP support? My VoIP provider (Callcentric) are currently experiencing major issues, and one of their suggestion to mitigate impact was to use 3rd party DNS servers as some don't properly resolve DNS SRV queries. This is copied from their status update page:
Update 10/19 - DNS SRV
We have received reports that some users are having problems using our DNS SRV based servers.
This is specifically because the new list of servers returned is not properly parsed by some DNS servers due to the size of the information, or not being returned at all. As such, we recommend using different DNS servers in your router and/or device if you are experiencing problems.
We have tested the servers below and found that they resolve our SRV records properly:
Same problem on my end. Had to use DNS servers supplied on CC's webpage, within my device, to resolve.
Using Teksavvy's DNS servers resulted in registration failure on my device.
I was having lots of trouble with callcentric as well. both their recommend opendns and teksavvy were failing. i had to disable these two options to get it working again.
Use DNS SRV
DNS SRV Auto Prefix
They say it should work with either DNS SRV or not, and mine is still using it and registers properly. Teksavvy's DNS weren't working with DNS SRY set to yes. When I changed to their recommended DNS servers in my 3102 it started working.
Can we have an detailed answer from Teksavvy on this one?
