What differentiates PHCTelecom's direct routes from generic aggregators?

Unlike aggregators that resell traffic through unknown third parties, PHCTelecom maintains direct carrier interconnections across 20+ markets in Latin America and the Caribbean. This eliminates unnecessary network hops, keeps latency low, and eradicates False Answer Supervision (FAS) or CLI loss.

How do you guarantee the delivery of transactional SMS and OTP codes?

We operate direct SS7/SMPP binds with local MNOs. For time-critical traffic (such as banking 2FA or verification codes), our dispatch pipelines prioritize traffic with guaranteed handset delivery in under 2.5 seconds and complete DLR receipts.

Can we test voice quality and CLI routes prior to signing a commercial agreement?

Yes. We provision test accounts with pre-loaded balance for qualified operators and enterprises to evaluate ASR, ACD, NER, and SIP signaling latency directly against your IP-PBX or Softswitch.

Which codecs and signaling protocols are supported on your SIP trunks?

We support standard RFC 3261 SIP signaling over UDP, TCP, and encrypted TLS, wideband Opus and G.722 codecs, as well as industrial standards G.711a/u and G.729AB. Authentication is available via IP ACL or Digest credentials.

How is real-time anti-fraud protection implemented?

Our network continuously monitors signaling patterns using predictive AI models. We instantly block International Revenue Share Fraud (IRSF), high-rate destination pumping, call flooding attacks, and CLI spoofing in sub-second timeframes.
