What It Is

GoTrunk is a SIP Trunking service from Level 7 Systems, aimed at businesses that already have their own IP-PBX. It replaces traditional ISDN/phone lines with internet voice, connecting a PBX to the PSTN for local, long-distance, international, mobile, and emergency calls. It also supports free internet calls between SIP endpoints, and can be combined with its sister service VoIPstudio to create a hybrid setup: SIP Trunking at headquarters and Cloud PBX for branches or home offices.

Core Capabilities

In terms of channels, the public materials focus only on voice/VoIP/SIP Trunking, with no mention of email, SMS, or IM. For coverage, the website provides entry points for the United States, the United Kingdom, Australia, Canada, Spain, and International; virtual numbers are available in more than 50 countries, and the infrastructure references three data centers in the UK, the US, and Japan. On performance, GoTrunk highlights built-in redundancy, disaster recovery options, real-time call quality monitoring, and real-time CDRs. However, its terms also state that VoIP service quality depends on broadband, ISP, power, and maintenance conditions, and cannot be guaranteed to be identical to traditional PSTN service. For integration, it is suitable for IP-PBX systems such as Yeastar, supports IP ACL/password authentication and multiple codecs, and CDRs can be retrieved via FTP, but no explicit REST API was found.

Pricing and Compliance

Pricing is positioned as low-barrier: a 30-day free trial with no credit card required, with examples showing a $1 setup fee and $1 monthly fee. Inbound calls are free, internet calls between SIP endpoints are free, and outbound calls to landlines/mobile numbers are billed by destination rate, charged per second with no call setup fee. It supports bank transfer, credit/debit cards, and USD/EUR/GBP. On compliance, GoTrunk provides terms, an acceptable use policy, complaints handling, privacy, and cookie policies. Emergency calling supports 911/112/999, but may be unavailable during internet or service outages; geographic numbers also require the user’s location to match the relevant area.

Pros, Cons, and Who It’s For

The advantages are no long-term contract, relatively transparent rate structure, per-second billing, broad number coverage, and strong PBX compatibility. It is suitable for SMBs with technical teams, multinational offices, call centers, and organizations looking to replace ISDN. The downsides are that it requires an existing IP-PBX or configuration experience, and the public pages lack detailed hard metrics such as destination rates, SLA, and answer-seizure ratio. Number port-out fees apply, and prepaid subscription payments are generally non-refundable.

Access from China

The scraped text does not provide information on network accessibility from mainland China, RMB payments, or local compliance, so China access is unknown. Teams in China considering GoTrunk should specifically test SIP registration, voice quality, latency, payment, and number compliance. For domestic-facing use cases, local alternatives such as carrier enterprise voice services and Alibaba Cloud voice services should also be evaluated.
