Make Sure Your Hosted VoIP Service Passes Interoperability Tests

Interoperability is amongst probably the most essential options of a provider grade Hosted PBX resolution. Enterprises and carriers hate surprises, particularly with regards to making Hosted cellphone service work with units corresponding to SIP telephones (Softphones, hardphones), SBC (Session Border Controllers) and different IP tools.

Compliance to requirements

It’s endorsed that every one Hosted IP PBX options be totally compliant with the IETF RFC 3161 specification for SIP protocol. This can be a fundamental requirement to make sure that the hosted PBX will have the ability to interoperate with different SIP primarily based units. There’s nothing worse than having a phone system that drops calls from sure SIP units simply because it can’t perceive a number of headers within the incoming message.

I’ve seen many Hosted VoIP techniques drop calls with regards to superior options corresponding to SIP Privateness and Nameless calling. That is primarily as a result of they don’t perceive sure headers within the incoming name messages and have no idea what motion needs to be subsequently taken.

Heterogeneous networks are the longer term

Giant organizations select totally different distributors for varied community elements. For example, an organization might procure Counterpath telephones for its US workplace, Snom hardphones for its UK workplace, OnSIP as its IP PBX resolution and a Nextel Session Border Controller. In such instances, it’s essential that every one community components are totally interoperable with one another. It isn’t possible for a corporation to exchange any community aspect just because it can’t work with merchandise from different distributors. From a monetary perspective, a hosted PBX with poor interoperability with different units is an ideal recipe for catastrophe.

Appropriate Configuration

With the intention to direct calls accurately, many enterprise VoIP suppliers require right interoperability configuration. If calls to locations exterior the IP community are failing, it could be as a result of the calls are routed via switches which might be related to the PSTN. {Most professional} hosted VoIP distributors present the interoperability configuration data on their web site.

Testing, Testing and extra Testing

One of the best ways to make sure that a service is excessive on interoperability scale is to check it rigorously and check it usually with an put in base of enterprise communication techniques.

Keep Updated with newest requirements

VoIP know-how has superior at an incredible tempo over the previous couple of years and it’ll proceed to evolve within the coming years as nicely. Due to this fact, it’s essential for hosted enterprise VoIP distributors to remain on prime of the most recent requirements and adjustments in know-how to make sure most interoperability of their product choices. Additionally it is greatest to search for a very requirements primarily based service in order to make sure that all the pieces they’re providing is appropriate with the most important variety of third occasion platforms, units, and options. The very last thing you need is a walled backyard.


Interoperability points have offered critical challenges to integrators and Hosted VOIP Service suppliers because the earliest PBX installations. Due to this fact, it’s sensible to decide on suppliers with confirmed interoperability with all main manufacturers of softswitches that make it simple for carriers and enterprises to deploy future-proof communications options rapidly and profitably at present.
