The SIP object is a child of the Signaling object. It represents the NE's SIP capability (both subscriber access and SIP trunking) and provides status information.
This object is pre-configured (configuration information is delivered with the NE), and you cannot create or delete it.
![]() |
Deactivating this object suspends all SIP communications for the NE; subscribers using SIP will be unable to make or receive calls, and calls cannot be routed or received over SIP trunks. You will be prompted to confirm deactivating the object. |
Parameter |
Access |
Description |
Server name | Change Inactive | The server name used in SIP messages to identify the NE. Set this to an IP hostname, which must be externally resolvable using DNS to the Virtual IP address of the NE (as specified in the NE CRAFT interface). Alternatively, you can specify the Virtual IP address itself. |
SIP retransmit timer (T1) | Change | Timer for retransmitting SIP signaling requests if a response is not received. To achieve optimum network performance and to minimize call setup delay, set this timer to a value slightly greater than the average round-trip time for SIP signaling requests between the NE and SIP devices in your network. Range: 125 - 1000 milliseconds. The default is 250 milliseconds. Contact MetaSwitch support if you need help with determining the right value for this timer. |
