Sharing a Fax Gateway Multiple RightFax Servers
Have you ever wondered if you could use a shared fax gateway to communicate with multiple RightFax servers for inbound and outbound faxes?
The short answer is YES you can.
We’ve recently completed this project for one of our major North American customers where they had three independent Line of Businesses (LOBs), each having their own RightFax server environment each with a legacy Dialogic TR1034 digital fax card and a dedicated T1 line connected to each.
One of the main project drivers was to virtualize each RightFax server (the benefits of which should be clear to most businesses these days, but if you need help on this give us a call). The main obstacle to virtualizing each RightFax server was the physical legacy fax board cards which resided on the physical servers. The solution to this problem as you might already be aware is Fax over IP (FoIP).
Based on our client’s clear requirements and limited budget, Connectis Group proposed to implement a shared OpenText Fax Gateway (OTFG) with a single combined T1 line (instead of 3 fractional T1s) for their new RightFax infrastructure telco connectivity. The solution would result in significant operational cost savings by eliminating their independent fractional T1 lines and combine them all in a single T1 line and also a single shared fax gateway instead of three. While its true using a single Gateway exposes the customer to a single point of failure being the single gateway, they were prepared to overlook the risk in favour of the cost savings.
Here’s a high-level view of what the new RightFax server environment architecture would look like.
Routing Inbound Calls
OTFGs have the capability to route the inbound calls based on their destination phone number. As this was a customer requirement, we configured the gateway to route the inbound calls based on the destination phone prefix (DID) of the called number to the appropriate RightFax server, which would in turn route the fax to the intended recipient.
Routing Outbound Calls
Each of the LOBs had a specific quantity of licensed RightFax server FoIP channels. Since the number of channels on the RightFax server had to be ‘one to one’ equivalent to the number of channels available to the server on the T1 line, we replicated this scheme by configuring 3 Trunk Groups in OTFG and each Trunk Group had been assigned the equivalent number of channels as the appropriate RightFax server was licensed originally for. With this configuration, the calls originated from each of the RightFax servers would be routed to the appropriate Trunk Group and go out to the telco based on the source IP of the FoIP traffic.
This typical problem demanded a creative solution, which satisfied our client needs and saved them a bundle. We have several solutions that can be employed to resolve telephony specific issues including cloud based faxing and eliminating the RightFax server all together and switching the client to our internal fax cloud hosted in Canada.
