Adding an SIP Interface

The MA5600T/MA5603T/MA5608T exchanges the signaling and protocol packets with the information management system (IMS) through an SIP interface. To ensure uninterrupted signaling and protocol packet exchange, ensure that the status of the SIP interface is in a normal state after you add it.

Context

  • One MA5680T/MA5683T/MA5608T supports up to eight SIP interfaces. Each SIP interface can be configured with the interface attributes separately.
  • The SIP attributes configured for an SIP interface take effect on this interface only.
  • The attributes of an SIP interface, including the signaling IP address, media IP address, transport-layer protocol, port ID of the transport-layer protocol, IP address (or domain name) of the proxy server, port ID of the proxy server, home domain name, profile index, are mandatory. In addition, the attributes of an SIP interface must be consistent with those configured on the IMS side so that the status of the SIP interface is normal.

Configuration Flowchart


Procedure

  1. Query the current voice protocol running in the system. Run the display protocol support command to query the voice protocol that is currently supported by the system.
    • If the system voice protocol is the SIP protocol, go to Step 6.
    • If the system voice protocol is not the SIP protocol, go to Step 2.
  2. Query the current MG interface in the system. Run the display if-mgcp all or display if-h248 all command to query whether an MGCP interface or an H.248 interface currently exists in the system.
    • If there is no such an MG interface, go to Step 4.
    • If there is such an MG interface, go to Step 3.
  3. Disable and delete the MG interface.
    1. Delete the user data of this MG interface, and then run the shutdown(mgcp) or shutdown(h248) command to disable the MG interface according to the protocol type of the interface.
      NOTICE:
      This operation interrupts all the ongoing services carried on the MG interface. Hence, exercise caution when performing this operation. Before performing this operation, you must check whether the operation is allowed.

    2. Run the undo interface mgcp or undo interface h248 command to delete the MG interface.
  4. Change the system-supported voice protocol to SIP. Run the protocol support command to change the system-supported voice protocol to SIP.
  5. Save the configuration data and restart the system. Save the configuration data by running the save command. Then run the reboot command to restart the system to make the new configuration data take effect.
  6. Run the interface sip command to add an SIP interface.
  7. Run the if-sip attribute basic command to configure the basic attributes of the SIP interface.
    NOTE:
    • Between proxy IP and proxy domain, which are basic attributes, at least one attribute must be configured. If both attributes are configured, the system determines which attribute is used according to the configured address mode of the proxy server.
    • The profile index must be configured.

  8. Run the if-sip attribute optional command to configure the optional attributes of the SIP interface. The optional attributes include some new service types supported by the SIP interface, such as the conference call, message waiting indicator, UA-profile subscription, and REG-state subscription, and also include the SIP proxy configuration mode. The optional attributes require the IMS-side support, and must be consistent with those on the IMA-side.
    After the configuration is completed, run the display if-sip attribute config command to query the attributes of the SIP interface.

  9. Reset the SIP interface. Run the reset command to reset the SIP interface for the new configuration data to take effect. Otherwise, the configuration data does not take effect but is only stored in the database.
    After the SIP interface is reset successfully, run the display if-sip attribute running command to query the running status of the SIP interface. If the active (or standby) proxy is up, the SIP interface is normal.

Example

Assume that: the media IP address is 10.10.10.13, signaling IP address is 10.10.10.13, transmission protocol is UDP, port ID is 5000, active proxy server IP address 1 is 10.10.10.14, port ID of the active proxy server is 5060, active proxy server domain name is proxy.domain, standby proxy server IP address 1 is 10.10.10.15, port ID of the standby proxy server is 5060, home domain name is sip.huawei.com, and profile index is 1. To configure the attributes of SIP interface 0, do as follows:
huawei(config)#interface sip 0
huawei(config-if-sip-0)#if-sip attribute basic media-ip 10.10.10.13 signal-ip 10
.10.10.13 signal-port 5000 transfer udp primary-proxy-ip1 10.10.10.14 primary-pr
oxy-port 5060 primary-proxy-domain proxy.domain secondary-proxy-ip1 10.10.10.15 
secondary-proxy-port 5060 home-domain sip.huawei.com sipprofile-index 1
huawei(config-if-sip-0)#reset                                                   
  Are you sure to reset the SIP interface?(y/n)[n]:y                            
huawei(config-if-sip-0)#                                                        
  Resetting SIP interface 0 succeeded                                           
huawei(config-if-sip-0)#display if-sip attribute running
  ------------------------------------------------------------                  
  ...//The rest information in response to this command is omitted.
  Primary Proxy State                  up   //Indicates that the SIP interface is in the normal state.
  Secondary Proxy State                down 
  ...
  ------------------------------------------------------------
