Howdy all, I'm trying to extend VOIP phones over a site to site VPN (meraki gear).

Primary network (hosting IPO 500 v2)

Network: 192.168.2.0/23

Router: 192.168.2.254

Avaya IPO: 192.168.3.15 | 255.255.254.0

Route in IPO: 0.0.0.0 | 0.0.0.0 | 192.168.2.254

Remote network (where a few 1608-i deskphones will be)

Network: 192.168.4.0/24

Router: 192.168.4.254

Phone: * getting subnet conflict when I try to assign a .4 IP with .3 call server on /24, so statically assigning 192.168.4.25 | 255.255.0.0

I suspect that I need to widen the range of the IPO 500v2, but am not certain. From remote network I can ping back to IPO @ 3.15, but from the 3.15 cannot ping back to the IP of the phone (can to other devices on the network).

Per: PSX_Defector in [URL unfurl="true"]https://community.spiceworks.com/topic/134445-how-to-setup-avaya-ip-office500-on-a-site-to-site-vpn[/url] this should be plug and play once I get the addressing and routes right. Correct? I previously had the IPO subnet opened up to 255.255.0.0 but then I was noticing the phone trying to ARP to find the 3.15 file server and call server. The router/VPN doesn't support proxy arp.

Can anyone clarify if widening the IPO subnet @ the main office is indeed the best next step?

Thanks in advance for helping.

Nope.

You have a routing issue pure and simple.

Your addressing looks ok apart from where you statically use a 16 bit mask.

Take Care

I have always wished that my computer would be as easy to use as my telephone.
My wish has come true. I no longer know how to use my telephone.

Indeed, you are causing a clash by using the wrong mask :-)

You also should not get a subnet conflict as long as the phone gets the default gateway entry.

Roger that, thanks for your help guys! I've seen your work in other parts of this forum, and it's all solid advice. I'll look further into the subnet conflict error for resolution.

192.168.4.25 with 255.255.0.0
is your problem, your subnetmask tells the phone that your IPO is on the same network so just broadcasting to it and not going via the default gateway. You have to change it to 255.255.255.0 which is most likely your remote network or you can also use the 255.255.254.0 as that would also go via the default gateway because only the 192.168.4.0 and 192.168.5.0 would be considered local.
Hope I am making sense it is late already.
