Use SIP trunking and save 30%+ on your phone bill.
As companies reevaluate how communications will support their business now and going forward, they will rely on the secure, proven capabilities of Session Initiation Protocol (SIP) trunking to accelerate digital transformations and substantially lower phone bills. With the impending decommissioning of TDM services around the world, they have additional incentive to do so. Gartner forecasts that by 2022, all network service providers in North America and Western Europe will announce the end of support of ISDN PRI service. They expect that by 2025, only a few providers in Europe will support the service.

With the ability to quickly connect on premise phone systems to the internet, SIP trunking provides an easy way to start moving communications off TDM services, accelerate the migration of communications to the cloud and start saving money that can be reinvested into more strategic initiatives. SIP trunking’s ability to support voice, video and messaging means you can deliver the communication channels employees need to be productive and connected with customers.
The promise of SIP trunking spans a wide range of uses—from wholesalers enabling traffic across the carrier networks, to companies adding international connections, to a company needing a short-term connection as part of their transition to the cloud.
The elegance of SIP trunking—and what makes it viable across this wide spectrum of uses—is that it looks and behaves like one large network.

How does it work with 8x8?
SIP trunking is essentially just a SIP connection between 8x8 and your environment to enable SIP in/out calling over the internet or MPLS. It could be to a PSTN gateway, an SBC or even an on premise IP-PBX. With an 8x8 SIP Trunk, here’s how it works:
Once the SIP trunk is connected, the calls will route from the PBX through the 8x8 SIP trunk to access the public internet and then be routed through 8x8’s network of tier one carriers. No more connection to your local phone company for expensive MPLS line rental.

Different types of SIP trunk deployments.
Enterprise SIP trunking has changed communication so radically in the last 20 years that it's hard to remember what communication was like without it. Quietly and incrementally, trunking has been shaping our idea of how, when and where we stay in contact with our customers and service providers. Yet, over this same time, many companies have chosen to slow down or push out investments in their communication technology. Recent events have magnified the consequences of those decisions. Technology and business leaders are now looking to accelerate digitization of their business while also becoming more operationally efficient. SIP trunking has many benefits, but one of them is extremely important right now: the ability to start saving money that can be reinvested into strategic initiatives. We see SIP trunking being deployed in three main ways:
- Wholesale communication providers
- Enabling international connections
- Short-term bridge to UCaaS/CCaaS
- Facilitating cloud migration

Enabling international connections.
The global economy depends on every company’s ability to connect headquarters with each of their international locations. SIP trunking is a cost effective way to quickly establish communication links between the HQ and satellite office locations. For example, a company headquartered in Hong Kong may want to expand operations in the US. They can quickly set-up a SIP trunk to enable cost-effective communications between the two locations.

Short-term bridge to UCaaS/CCaaS.
Companies already using 8x8 cloud services can connect to another part of their business, or a new acquisition, that’s still using an on-premises phone system to enable extension-to-extension dialing between the on-premises system and the 8x8 phone numbers.
The characteristics of this approach include:
- 8x8 can set up a fallback rule for extension-to-extension dialing
- Requires a public IP/port
- No PSTN connections, only extension-to-extension (a standard SIP trunk can be added)
- Purpose-built adapters with redundancy in each data center
- In/out adapters

Facilitating cloud migration.
Migrating communications from an on-premises PBX to the cloud can feel like a daunting task, especially for a large enterprise with multiple offices and communications tools around the world. Deploying a SIP tie trunk between the on-premises PBX and the new cloud communications platform will ensure employees can continue to be productive during a migration. An 8x8 SIP trunk for cloud communications delivers:
- Dial plan mapping
- Full PSTN replacement in 40+ countries
- Phone numbers in 90+ countries
- Shortcodes
- Automated failover

Are SIP trunking and VoIP the same thing?
Although these terms are often used interchangeably, they are not the same thing. Voice over IP (VoIP) describes a way to conduct phone calls over the internet.
SIP is a protocol used to start, maintain, and end voice, video and messaging communication sessions in VoIP applications.
So while all SIP trunking is used to deliver VoIP, not all VoIP uses SIP.
