The following SIP timers can be configured from the admin console.
T1
Amount of time, in milliseconds, for a network round trip delay for timer T1 for the RFC 3261 specification. The value is used as a base for calculating some timers and is relevant for all types of transactions, such as client, server, invite, and non-invite transactions.
Data type Integer Default 500
A
Specifies, for UDP only, the amount of time, in milliseconds, before retransmitting invite requests for timer A for the RFC 3261 specification. This setting is relevant for the invite client transaction.
Data type Integer Default T1
B
Amount of time, in milliseconds, for the invite client transaction timeout timer (timer B) for the RFC 3261 specification.
Data type Integer Default T1*64
E
Specifies, for UDP only, the amount of time, in milliseconds, before the retransmission of the initial non-invite request for timer E for the RFC 3261 specification. This setting is relevant for the non-invite client transaction.
Data type Integer Default T1
F
Amount of time, in milliseconds, for the non-invite transaction timeout timer (timer F) for the RFC 3261 specification. This setting is relevant for the non-invite client transaction.
Data type Integer Default T1*64
G
Amount of time, in milliseconds, before retransmission of an initial invite response for timer G for the RFC 3261 specification. This setting is relevant for the invite server transaction.
Data type Integer Default T1
H
Amount of time, in milliseconds, to wait for an acknowledgement (ACK) receipt for timer H for the RFC 3261 specification. This setting is relevant for the invite server transaction.
Data type Integer Default T1*64
J
Amount of time, in milliseconds, to wait for non-invite request retransmission for timer J for the RFC 3261 specification. This setting is relevant for the non-invite server transaction.
Data type Integer Default T1*64
T2
Maximum amount of time, in milliseconds, before retransmitting non-invite requests and invite responses for timer T2 for the RFC 3261 specification.
Data type Integer Default 4000
T4
Maximum amount of time, in milliseconds, for a message to remain in the network. This value is used as a base for calculating other timers for timer T4 for the RFC 3261 specification.
Data type Integer Default 5000
I
Amount of time, in milliseconds, to wait for an ACK retransmission for timer I for the RFC 3261 specification. This setting is relevant for the invite server transaction.
Data type Integer Default T4
K
Amount of time, in milliseconds, to wait for non-INVITE response retransmissions for timer K for the RFC 3261 specification. This setting is relevant for the non-invite client transaction.
Data type Integer Default T4
D
Amount of time to wait, in milliseconds, before retransmission of the invite response for timer D for the RFC 3261 specification. This setting is relevant for the invite client transaction.
Data type Integer Default 32000
