SIP Trunk configured for DNS SRV not getting INVITES

This document was generated from CDN thread

Created by: Ashraf Khandwalla on 26-03-2010 02:52:42 PM
I have a SIP Trunk configured with a DNS SRV destination address; a device configured for automatic recording; a recording profile, etc configured to associate the trunk to the device. 
None of my servers in the DNS SRV record get a SIP INVITE when the device answers the call.
A quick look at the Call Manager sdi logs seem to indicate a DNS query failure.
03/25/2010 16:53:20.660 CCM|//SIP/SIPDns(1,53,1)/wait_SdlDnsSrvRecordRsp: (DNS A or AAAA query called as SRV query Fail), ReqType=1,serversused=0

The query is successful when I run it in the Call Manager CLI:
utils network host srv

Local Resolution:
Nothing found

External Resolution: SRV 0 0 5060 SRV 0 0 5060 SRV 0 0 5060

The query is also successful when I run it using nslookup.
I am not sure why the CLI would be able to run the query but the CCM service would not.
Appreciate any ideas anyone might have. Thanks.
CCM version 7.1.3

Hi Ashraf,
Upon reading your descritption of the issue, it seems we will need ccm sdi/sdl traces in detailed level, with "enabled sip stack tracing" selected for analsying this issue.
Kindly open a Developer Support Service Request  with the trace, if you have an active Developer Services Subscription contract for detailed assistance:
