PSTN Call is an enterprise-focused VoIP provider and consulting service, mainly offering PSTN outbound calling, DID/TFN inbound numbers, SIP Trunking, and implementation, troubleshooting, and support for open-source communications systems such as Asterisk, FreeSWITCH, Kamailio, and OpenSIPS. It is not an email service provider, and the site does not present standalone SMS or IM channels. Its core positioning is voice communications and VoIP infrastructure.
On the connectivity side, voice is the main focus. It supports international outbound calls, DID inbound, Toll-Free forwarding, SIP URI/IP/PSTN forwarding, Failover, Caller ID, DTMF, call recording, TLS/SRTP, and more. In terms of coverage, it claims global outbound calling, with rate tables listing countries including the United States, Canada, the United Kingdom, China, and India. For inbound numbers, it says it supports 60 countries, though some countries require local ID and proof of address for activation. For performance, the official site mentions a 99.95% uptime SLA, enterprise-grade voice quality, and high availability, but it does not publicly provide auditable metrics such as ASR, ACD, PDD, or answer rates.
Pricing is mainly usage-based per minute, with no connection fee, 1/1 billing, a minimum top-up of USD 25, and a USD 1 test credit. Example rates include USD 0.0055/min for outbound calls to the United States and USD 0.065/min to China. The site also advertises rates as low as USD 0.001/min to U.S. prefixes, but the actual pricing should be confirmed against the in-account A-Z rate list or with sales. Inbound DID numbers typically include a per-minute charge, setup fee, and monthly rental. For integration, it provides a self-service portal, IP and prefix management, and CDR lookup, and can assist with PBX configuration and integrations with Twilio, Plivo, Nexmo, MessageBird, Exotel, and others. However, the site does not show full API documentation.
Its strengths are a relatively complete voice product line, better rate transparency than many small VoIP sites, and consulting coverage for mainstream open-source communications stacks. It is suitable for call centers, VoIP resellers, remote teams that need local numbers, voice verification codes, and international calling services. The drawbacks are limited information about the companyβs location, credentials, and route quality verification; relatively high-level compliance statements; and some typos and repeated wording on the official site. The rate descriptions also need to be cross-checked.
The site does not provide information about access from mainland China, payment availability, or ICP filing status, so china_access can only be treated as unknown. Payment shows PayPal, while Stripe is still in progress, which may create foreign-currency and invoicing limitations for Chinese businesses. If you need a more mature global CPaaS platform with stronger documentation, compare Twilio, Plivo, Vonage/Nexmo, and MessageBird. If the priority is locally compliant voice service, Chinese carriers or local cloud communications providers should also be evaluated.
