Hosted VoIP Solution: Transitioning To SIP Trunking

June 30, 2012 | Comments: 0 | Views: 132

Is your business considering transitioning to SIP trunking? Before you commit to a specific SIP carrier, there are a number of factors to consider.

Before we get into that however, let's start at the beginning. What is SIP? SIP or, Session Initiation Protocol Trunking is a converged IP service that will deliver a number of services on a single access circuit such as IP or MPLS service.

  • Local voice service
  • Long distance voice service
  • Data WAN service over a single access circuit.

There are big differences in the way SIP is provisioned which can have significant impacts on cost, functionality and emergency back-up.

With SIP, your business can achieve lower IT costs by sharing network resources for both voice and data services. This also include transitioning local services to SIP further lowering cost and simplifying your network. Thanks to number portability, most businesses will be able to retain their existing telephone numbers making the transition seamless without any disruption to your business communications.

SIP Trunking is not a line side service similar to a Hosted VoIP Solution. Busy signaling, call control, transfers, conferencing, voice mail and other features must be provided by your VOIP enabled phone system.

It is also important to understand that SIP can either be IP or MPLS based, and that there are huge differences between the two. With MPLS provisioned SIP service your phone service will ride on a secure private network where quality of service (QOS) can be guaranteed. This is not true of IP based SIP which rides on the public unsecured network. IP based SIP cannot guarantee QOS and instead offer service based on best efforts.

MPLS based SIP is also customizable and can provide network based allocation of talk paths on demand thereby allowing all locations within the network to share SIP trunks. With IP based SIP service, each location must have its own SIP trunks, much like local PSTN service. SIP trunks cannot be shared or allocated within the network. By allowing the sharing of resources MPLS based SIP allows for more unified communications management and in most cases greater cost reductions.

Another factor to consider when selecting a carrier is whether or not they offer toll free SIP. If not, your business will have to continue to maintain separate trunks for high volume toll free termination adding additional cost.

Also, find out if the service is burstable? In times of high demand can your SIP provider provide more talk paths if needed. This is a terrific feature for any business that has occasional peak calling both for in and outbound calls.

For businesses that have both domestic and international locations that they would like to transition to SIP, options are evolving. International MPLS SIP will start coming on line in 2012 but is not now offered. However, MPLS based domestic SIP can be combined with IP based international SIP for a cost effect temporary solution as MPLS SIP availability expands.

Finally, it's very important to consider what type of emergency back-up the carrier is offering. Carriers that offer wireless integration allow seamless failover to mobile back up devices. Most SIP providers do not offer this type of converged service and you will need a network based back-up plan to be implemented which further adds to your monthly cost and management expenses.

In summary, be careful about choosing a SIP provider based on cost per SIP trunk alone. For all of the reasons mentioned above, cost per trunk may be less important than the way the service is provisioned.
