4. - SBC SIP Interfaces

It’s now time to create a SIP service associating the IP in network interfaces with realms configured previously. 

 On the CLI lets first create the External SIP interface: 

 PCOSBC# config t

PCOSBC(configure)# session-router

PCOSBC(session-router)# sip-interface 

PCOSBC(sip-interface)# realm-id External

PCOSBC(sip-interface)# sip-ports 

PCOSBC(sip-port)# address 192.168.10.201

PCOSBC(sip-port)# port 5060

PCOSBC(sip-port)# transport-protocol udp

PCOSBC(sip-port)# allow-anonymous all

PCOSBC(sip-port)# 

PCOSBC(sip-port)# done

sip-port

 address 192.168.10.201

 port 5060

 transport-protocol UDP

 allow-anonymous all

 multi-home-addrs 

 ims-aka-profile 

   

 Remember to issue the done command when completing the sip-port element and exit to jump to the sip-interface branch and issue the done command. 

 Setup SIP Interface for Internal 

 PCOSBC(configure)# session-router 

PCOSBC(session-router)# sip-interface 

PCOSBC(sip-interface)# realm-id Internal

PCOSBC(sip-interface)# sip-ports 

PCOSBC(sip-port)# address 192.168.2.101

PCOSBC(sip-port)# transport-protocol UDP

PCOSBC(sip-port)# 

PCOSBC(sip-port)# allow-anonymous all

PCOSBC(sip-port)# done

sip-port

 address 192.168.2.101

 port 5060

 transport-protocol UDP

 allow-anonymous all

 multi-home-addrs 

 ims-aka-profile 

 

 

PCOSBC(sip-port)# exit

PCOSBC(sip-interface)# done

sip-interface

 state enabled

 realm-id Internal

 description 

 sip-port

 address 192.168.2.101

 port 5060

 transport-protocol UDP

 allow-anonymous all

 multi-home-addrs 

 ims-aka-profile 

   

 An easy way to confirm the association of the IP address with the correct realm is issuing the command: show  virtual need to save active config to display the information 

   

 PCOSBC# show virtual

intf phy-name vlan ip-addr realm type

0/0 External 0 192.168.10.201 External sip-port

1/1 Internal 0 192.168.10.101 Internal sip-port
