To register to alternate SIP server, use either of the following procedure:
If both of the above configurations are present, the SIP Trunk Group Configuration takes precedence over the IPSP Configuration.
IPSP Configuration
To configure an alternate SIP server using IPSP configuration, perform the following steps:
- Configuring Path Check for IP Address or FQDN
- Configuring IP Signaling Profile
- Configuring the Internal Expires Timer
- Configuring Registrar Recovery flags in IP Signaling Profile
Configuring Path Check for IP Address or FQDN
This feature requires Pathcheck support using OPTIONS Ping and ARS static blacklisting to detect the reachability of a particular IP/FQDN.
For IP Address
set profiles services pathCheckProfile PATH1 protocol sipOptions sendInterval 60 replyTimeoutCount 1 recoveryCount 1 set addressContext default zone ZONE_AS ipPeer PEER_AS ipAddress 10.54.80.94 ipPort 6274 set addressContext default zone ZONE_AS ipPeer PEER_AS pathCheck profile PATH1 state enabled
For FQDN
set profiles services pathCheckProfile PATH1 protocol sipOptions sendInterval 60 replyTimeoutCount 1 recoveryCount 1 set addressContext default zone ZONE_AS ipPeer PEER_AS1 policy sip fqdn example.com fqdnPort 6274 set addressContext default zone ZONE_AS ipPeer PEER_AS1 pathCheck profile PATH1 hostName abc.example.com hostPort 6274 state enabled
Configuring IP Signaling Profile
set addressContext default zone ZONE_AS sipTrunkGroup TG_SIPART_AS policy signaling ipSignalingProfile DEFAULT_SIP
Configuring the Internal Expires Timer
set addressContext default zone ZONE_AS sipTrunkGroup TG_SIPART_AS signaling registration insideExpiresMinimum 3600
Configuring Registrar Recovery flags in IP Signaling Profile
set profiles signaling ipSignalingProfile DEFAULT_SIP commonIpAttributes registrarRecovery registerToAlternateOnPrimaryDown enable revertToPrimaryOnRecovery enable deRegisterAlternateOnPrimaryRecovery enable overrideInternalExpiresTimer enable
- The
registerToAlternateOnPrimaryDown
flag must be enabled to viewoverrideInternalExpiresTimer
andrevertToPrimaryOnRecovery
flags. - The
revertToPrimaryOnRecovery
flag must be enabled to viewdeRegisterAlternateOnPrimaryRecovery
flag. - The IPSP flags can be configured only on Egress Trunk Group.
SIP Trunk Group Configuration
The CLI request queryPsxOnNextRefreshRegister
command is used to force PSX query on subsequent refresh REGISTER. This enables new routing information configured in PSX to reflect in SBC when registrations are active for a long period of time.
Any new registrations that are received after the command is executed are not affected by this command.

- The request
queryPsxOnNextRefreshRegister
command must be executed only on the Ingress Trunk Group. - The request
queryPsxOnNextRefreshRegister
command is applied to all the refresh REGISTERs on all active registrations, which are currently handled by SBC.
