How to configure Session Border Controller (SBC) as the next hop in Subscriber Feature Proxy (SFP)

Core Issue

The user is trying to accomplish this call flow:

Caller_III > SFP > SBC_Enterprize_B > SBC_Enterprize_A > SIPX > Caller_I.

Resolution

Configure SBC_Enterprize_B in the SFP as sg-element. The SBC should take care of the rest of the logic for communicating to Enterprize_A.

To configure an sg-element, perform these steps:

  1. Login to SFP Command Line Interface (CLI).

  2. Issue the dssfp>context route-mgmt command.

  3. Issue the dssfp[route-mgmt]>sg -s SBC_Enterprize_B command.

  4. Issue the dssfp[route-mgmt]>sg-element -s SBC_Enterprize_B -i IP -p PORT -t UDP command.

  5. Issue the dssfp[route-mgmt]>route -t KnownDomains -k Enterprize_A.com -o outbound -s SBC_Enterprize_B command.

  6. Issue the dssfp[route-mgmt]>commit -v "version number" command.
