• Quality voice services, and
• Potential for sophisticated interconnection.
Voice-over-IP phone service through a SIP provider isn't just significantly less expensive than a traditional public switched telephone network (PSTN) service. It also carries the benefit of more straightforward billing. With SIP Trunking, your organization can expect to pay a predictable amount calculated and billed by the total number of telephone lines (or call instances) you use monthly.
How Much Does SIP Trunking Cost?
The cost of SIP Trunking relies on several factors, including your vendor, equipment, implementation fees, and the ongoing monthly service fee you pay your vendor. Industry studies disclose that the average firm saves between 25-60% over phone service through a traditional telecommunications vendor by switching to SIP. Organizations with a high volume of long-distance or international calls usually have the potential to save the most significant percentage of costs.
A detailed pricing overview is below to understand the total cost of switching to SIP. Not every factor detailed below will apply to every organization, but all can impact your final price for setup and monthly service.
1. SIP Setup Fees
Numerous business-class SIP Trunking vendors charge a fee for starting a SIP service. Others provide free setup but may charge a higher monthly rate. The setup fee commonly covers the cost of consultation, implementation, and quality testing.
2. New Phone Lines
Suppose your organization is using the transition to SIP as an opportunity to extend to more phone lines and give direct inward dial (DID) numbers for extra users. In that case, there is a fee related to this. However, the one-time setup fee for all new DID is usually nominal.
Your organization is not needed to purchase DIDs, and may not need DID for each phone user. For example, some employees may only need extensions instead of numbers directly callable from an outside number.
3. Number Porting Fees
Your business has a legitimate claim to keep your number. Per the FCC(Federal Communication Commission) guidelines, your organization has a right to port over figures and retain the same contact details if you are shifting to SIP Trunking or varying business telecommunications unless you are also moving geographic locations.
Porting is among the most time-taking parts of the SIP Trunking implementation process. For large organizations, it may be a multiple-day process that includes several batches of porting and quality assurance testing post-ports.
4. Handsets
All SIP Trunking users will need an IP-compatible handset. The costs of this equipment investment will differ drastically based on whether you select a generic phone with primary features or a top-of-the-line brand designed for sophisticated conference room use. Name brand technologies are more pricey than generic models, and advanced features also increase the cost of the phone model. Your organization will be required to evaluate whether your users need some or all of the following features when selecting suitable handsets:
• 3-Way Calling
• Intercom
• Automatic Callback
• Call Transfer
• Call Forwarding
• Call Hold
• Speed Dial
• Call Waiting
• Inside/Outside Ringing
5. PBX Configuration
Organizations with legacy private branch exchange (PBX) technology that has not been formerly used for IP telephony may require acquiring a VoIP gateway to take advantage of SIP trunking with the vendor. The gateway or Integrated Access Device (IAD) links to the PBX and allows you to unlock some of the advantages of IP-based telephony.
While expenses of this gateway can differ significantly, your organization can await to pay between $500-$2000 for this equipment investment. Organizations lacking a legacy PBX may not have to buy a gateway to deploy cloud-based IP phone service.
