Failed to set up point-to-point SIP calls over TLS
Symptom
The UA could not set up point-to-point SIP calls over TLS when the basic voice gateway settings are
correct.
Solution
Check that:
•
The devices of both sides have certificates.
•
TLS policies have been configured.
•
TLS policies have been referenced in SIP client view.
•
TLS is specified as the transport layer protocol for outgoing SIP calls. (You can specify the
transport layer protocol in either VoIP voice entity view or SIP client view.)
•
Listening ports are enabled on both the calling device and the called device.
•
The number of the port corresponding to the destination address is set to 5061 for VoIP voice
entity.
