Configuration verification

SIP calls from Telephone 1111 to telephone 2222 are carried over TLS. You can view the information of all

TLS connections using the display voice sip connection tls command.

Configuring SIPS URL scheme for outgoing SIP calls

Network requriements

Two routers Router A and Router B work as SIP UAs. It is required that the SIP calls from Telephone 1111

to telephone 2222 use the SIPS URL scheme.

Figure 49 Network diagram

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 "Configuring TLS

carry outgoing SIP calls."

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 Security Configuration Guide.

1. Configure Router A:

# Configure the IP address of the Ethernet interface.

<RouterA> system-view

[RouterA] interface ethernet 2/1

[RouterA-Ethernet2/1] ip address 192.168.2.1 255.255.255.0

[RouterA-Ethernet2/1] quit

# 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.
