Mar 07, 2018
- Cisco Unified Communications Manager IM & Presence Service
Known Affected Releases
Symptom: When there is a problem with DNS server or network issues delaying reverse DNS query from CUP, the call setup time will take longer as CUP is still waiting for the response from DNS server. This is still true for the customer not using IP addresses in the configuration. Conditions: CUP is integrated with CVP as SIP Proxy server.
