Configuration procedure
You can use the SIPS URL scheme only when the transport layer protocol is TLS. Therefore, before
performing following configurations, you need to configure TLS for SIP as described in
TLS to carry outgoing SIP
When a call is initiated, the TLS listening port of the calling party must be open; otherwise, the call
connection cannot be established.
For information about how to configure the TLS policy, see HPE FlexNetwork MSR Router Series
Comware 5 Security Configuration Guide.
1. Configure Router A:
# Configure the IP address of the Ethernet interface.

# Reference the created SSL server and client policies for SIP. Specify TLS as the transport
layer protocol for both outgoing and incoming SIP calls; and specify URL scheme for the
outgoing SIP call as SIPS.
