Shared SIP Trunking: What VoIP Resellers Need to Know

SIP trunking is the process of using VoIP to connect a PBX to the Internet, enabling businesses to access the cost-saving and timesaving benefits of cloud-based telecom. Shared SIP trunking furthers the benefits to businesses by allowing them to share their SIP trunking services throughout multiple office locations, thereby further reducing costs and enhancing collaboration between branches. VoIP has experienced tremendous growth over the last five years, and offering shared SIP trunking will allow resellers to provide better service, enhance the experience of their clients, and strengthen their business relations.

How Does Shared SIP Trunking Work?

Shared SIP trunking allows businesses to share their SIP trunking services throughout all of their office locations, while utilizing the same account. Take, for example, a company with five different branches, each containing ten phone lines. With 50 lines total, they are likely spending a lot of money on their phone service. Sharing SIP trunks across locations will allow them to minimize the number of needed phone lines, thereby reducing their telecom bill.

By providing your customers with the number of SIP trunk groups they require, as well as all of the call paths needed by their business, they can share services among office locations and reduce their number of phone lines by up to 20 percent. For a business with 50 phone lines, that's a reduction of 10 lines, thus cutting their phone bill considerably.

What Are the Benefits of Shared SIP Trunking?

In addition to the obvious cost savings, businesses can receive additional benefits as well. Some of the key advantages include:

  • Having the ability to exceed their prepaid trunks and call paths automatically, with only a small surcharge applied.
  • Having added call routing features to enhance their business communication and reduce the number of missed calls.
  • Having an enhanced disaster recovery plan. With shared SIP trunking, businesses can avoid unexpected and unwanted downtime because all phone calls can be automatically transferred to different locations as needed. A loss of power has the potential to cost a business hundreds of dollars in missed revenue. Shared SIP trunking enables perfect business continuity, so if the phone network of one branch experiences complications, all of the calls can be forwarded to another branch.

With enhanced business continuity, your clients will strengthen their customer relations by never missing a call.


  • It's more efficient for the VoIP reseller. When clients share SIP trunking, it creates less work for the VoIP reseller as well. Take the company with five branches; before, you had to manage services for each branch individually. Once the branches share services, you have the ability to manage the VoIP of all branches simultaneously and can update their services collectively or individually as needed.

As a VoIP reseller, you need to offer your clients the best services for their business. For growing companies with multiple locations, shared SIP trunking offers them the most competitive pricing, while enhancing their communication abilities and strengthening their disaster recovery plan. VoIP has become increasingly popular. To stay ahead in the competitive marketplace, it's essential to offer the services most relevant to your clients, so you can strengthen business partnerships and watch your profits soar.
