Introduction
This document contains the preferred method of implementation to allow for full active-active setup in between vNAGs and SOPs
How to implement ?
SOP Configuration - SIP Trunk

Navigate to: Resources > Interfaces
There must be one FMU sip trunk to STR and to MAR for each SOP that needs connectivity to FMU.
Please refer to the Fusion (UC) setup guides for installation of a SIP Trunk.

Navigate to: Apply changes > Apply changes
SOP Configuration - In the SDF (or SDX)

Navigate to: Resources > IP Phones
Select the SDF/SDX that you want to install as Active-Active.
Change the parameters:
- SOP1 = sop key of the primary SOP.
- SOP2 = sop key of the secondary SOP.

Navigate to: Apply changes > Apply changes
vNAG Configuration

Navigate to: Resources > Interfaces
Select the EndPointAbstract resource (SIG1xxxx)
Change the parameters:
- SIP Server 1 IP Address = IP Address of the SOP1 (primary)
- SIP Server 2 IP Address = IP Address of the SOP2 (secondary)
Note: inverting primary with secondary could lead to dropped calls.

Navigate to: Apply changes > Apply changes
Note
Please be careful when you select primary and secondary SOPs, the configuration must match on both sides.
Warning: Make sure to use the Primary SOP (as specified by customer) with the Primary vNAG (Paille/STR) unless in fail-over mode.
