When the MA5620G provisions an SIP voice service, terminal users are often registered
by shelf ID or by slot ID (such as sip:0/22/3/1/1/hw32303131EF0EC641@ims.zj.chinamobile.com).
How are series of symbols like this are assembled?
The general format of “sip:0/22/3/1/1/hw32303131EF0EC641@ims.zj.chinamobile.com” is “sip:
where Channel is fixed to 0, and Rack is fixed to 1. So variable parameters are only Shelf, Port, Slot,
AN-ID and domain. Port indicates the port ID of a subscriber. Slot indicates the slot ID. Shelf indicates
the shelf ID. AN-ID indicates the name of an access node and is set by running the raio-anid command.
domain indicates the domain name, that is IMS domain name, and is set in the basic attribute
home-domain of the SIP interface.
Note: In terms of MA5620G, for the versions earlier than V800R305C00B133SPH006, Port, Slot,
and Shelf do not indicate actual port ID, slot ID, and shelf ID, but the real ones plus 1; for the versions
later than V800R305C00B133SPH006, the actual port ID, slot ID, and shelf ID comprise the IMPI.
After the SIP interface is enabled, the device, carrying IMS user private ID (IMPI) information,
registers to the IMS regularly. Users can view whether the IMPI assembled by the device meets
the requirement by using the DBwin tool. For details of configuration, refer to the MA5620G SIP
