Avaya IP Office 500v2 with two different WAN and SIP 1

[Maerad]

Hi guys,

I got a bit of a unique question and hope you can help me with that.

Our ISDN got canceled and we will change to a SIP Trunk soon. Right now we already use a SIP Trunk for one of our branch offices with some numbers.
The Provider for our new SIP Trunk also provides a new DSL Line, exclusively for his SIP Services, so I can't get a normal internet connection with it.

So I need to do the following:

- SIP Trunk old > connect with Internet Gateway
- SIP Trunk new > connect over the new, exclusive Gateway

The IP Office sits in a separate VLAN (300) with the phones over LAN1, LAN2 has a router with a dedicated, normal Internet line for Internet Access and the current SIP Trunk. This line will be gone with out ISDN.
Of course we have a separate line for our usual internet traffic.

After the change we will have ONE WAN line for Internet and ONE WAN with the dedicated line for the new SIP Trunk.

My first idea was:
- Internet Gateway with PFSense > LAN (VLAN 1 DATA, VLAN 300 Voice) > VLAN300 IP 10.65.64.123 as Gateway, Port 5060 gets routed 1:1 to the IP Office
- Avaya LAN1 IP 10.65.64.1, Routing in IP Office 0.0.0.0/0.0.0.0 / LAN1 / Metric 0
- Avaya LAN2 DHCP Client with dedicated line (I got a router from them I can't access and have to use with DHCP), Routing in IP Office to their internal Network (10.1.1.XX) with LAN2
- SIP for both trunks with Network topology for LAN1 OR LAN2, depending what I need.
- Port forwarding etc. was configured of course.

Well, it didn't work of course. When I pinged in status monitor the old SIP Trunk, it was telling me the right IP Address, BUT as gateway it used the LAN2 port. Not the LAN1.

So - any idea how I could do this or why the ip office behaves like that? Version is 9.0.12 (lastest service release)
Or any idea how I can do this?

Thanks!

Think getting a SBC would be the best option, in that case the IPO would just use the SBCs internal address.

You do not need to use DHCP client on LAN2, just find out what the router address is and statically assign an address on the LAN2 port with a route added to the SIP provider of course.
The issue you have is the IP Office will always use the default gateway learned by DHCP before any IP route entered is checked

Thanks for the answers - the DHCP part was right. After I disabled DHCP and did a manual setup, everything worked.

So no I have one SIP Trunk over the usual internet gateway (port mapping to 5060, but only for the sip network in firewall) and at the wan port I have the new trunk with the dedicated sip trunk. Works great!

Sounds like he deserves some pink love

The truth is just an excuse for lack of imagination.

You're right - I didn't even see that pink star...
