I'm trying to get auto discovery working for CMA, but I'm getting stuck in a "Unable to connect to the provisioning server" message. I run Wireshark and see the request from my computer to the DNS asking "Standard query SRV _cmaconfig._tcp", but the DNS responds with "no such name".
Attached is a screen cap of how my DNS admin configured the service. The text in the admin guide says I should have something like this: "__cmaconfig._tcp.wvus.org 86400 IN SRV 0 0 443 vtc.wvus.org".
Any hints where i messed up?
Solved! Go to Solution.

welcome to the Polycom community.
It looks like you are using two __ lines rather than just one _

Thanks Steffen. I followed the CMA doc with a copy and paste :)
I removed the extra "_" but find the same thing. Attached is the wireshark of the two marked frames. It is starting to look to me like the DNS is checking an external name server for this.
Am I right? if so, what do I tell my DNS admin? If not, ?

You are right, the dns lookup is going to the root DNS servers:
Your domain name is missing from the service lookups. I would check to see if the PC is part of a domain or not. You can also look the TCP/IP properties of the network connection you are using. There is a DNS tab which has some options about adding a suffix (aka you domain name). I would try this first and repeat your tests.

I am having this same issue. I have deployed two CMA4000 servers, and the CMA desktop clients cannot Auto Register with any of the CMA Servers. This is after creating a DNS Service Entry for them. The string we used is this:
__cmaconfig._tcp.nlng.net 86400 IN SRV 0 0 443 NLNGVCCMA001.nlng.net
where NLNGVCCMA001 is the server's DNS name.
Is there any issue with the string?
