Do I need to change any configs to allow the use of FOP2 connectivity using IPV6?

I am running Freepbx 2.11.0.38 on a CentOS 64 vm. I am running FOP2 v 2.2.7

I have recently enabled IPv6 on the asterisk server (dual stack), and can browse the Freepbx asterisk web interface via IPv6.

Any attempts to connect to FOP2 time out. I can log into the FOP2 server via ipv4 as normal.

In order to IPV6 enable the SIP server, I had to change the asterisk HTTP bind address from "0.0.0.0" (any IPv4 address) to "::" (any IPv4 or any IPv6 address).

Looking at netstat, I think FOP2 is still only listening on IPv4 addresses:

netstat -lnp | grep 4445
tcp        0      0 0.0.0.0:4445                0.0.0.0:*                   LIST                   EN      30108/fop2_server

Does FOP2 allow connection via IPv6? How do I enable it?
