Number porting

Paperless LNP in the UK, US, Canada, Netherlands, Germany, and a growing list. Document-based porting elsewhere. Typical lead time 3–10 business days, region-dependent.

Channel pooling — you pay for capacity, not per-DID lines

Traditional "channels per DID" pricing punishes hosted-PBX and contact-center patterns. Callivex pools inbound channels across all DIDs in your account, so a 200-DID hosted-PBX customer might only need 40 simultaneous channels.

Account-wide channel pool — DIDs share capacity
Per-DID channel caps available for fairness across tenants
Burst capacity on request (24-hour activation)
Inbound delivery to one or many SIP endpoints (round-robin or priority)
Per-DID failover targets (after-hours, overflow, full-busy)

# DID account — sample summary Account: hosted_pbx_b Active DIDs: 218 Channel pool: 40 simultaneous (burst 80) Countries: UK, IE, DE, NL, FR, ES Inbound delivery: 2× SIP endpoints, priority Failover: after-hours → voicemail Active calls: 14 / 40 Today inbound: 1,847 calls · ASR 41%

Address-of-use, regulatory KYC, lawful intercept

Many jurisdictions require an address of use, identity verification, or in-country registration before issuing local numbers. We handle the regulatory layer; you supply the end-user details.

UK Ofcom address-of-use compliance for geographic ranges
Bundesnetzagentur (DE), ARCEP (FR), AGCOM (IT) registrations
FCC regulatory delivery for US numbers (E911 where applicable)
Lawful intercept hooks where regulator-mandated, customer-transparent
End-user KYC retained per Privacy & GDPR policy
