Kenyan carriers, connected to your VoIP system properly
A VoIP system without carrier connectivity is just an internal communication tool. SIP trunking connects your 3CX or other VoIP platform directly to Kenyan carriers, Safaricom, Airtel, Telkom, so inbound calls from any number reach your system and outbound calls use local carrier rates. Sentire manages the entire SIP trunk provisioning process: carrier registration, authentication configuration, codec negotiation, and ongoing monitoring.
Why SIP over traditional PSTN lines?
Traditional analogue and ISDN lines are fixed, expensive to scale, and physically tied to a location. SIP trunks are software-defined, you add capacity instantly, add new numbers quickly, and pay per channel used rather than per line provisioned. For businesses already running a cloud PBX, SIP trunking is the logical connectivity layer.
Kenyan carrier integration
Safaricom SIP trunks
Safaricom Business SIP trunks support direct business number DDI (Direct Dialing In), competitive local call rates, and mobile termination to Safaricom subscribers at local rates. Sentire handles registration, authentication, and ongoing trunk management.
Airtel SIP trunks
Airtel Business SIP connectivity provides DDI numbers and mobile termination across the Airtel network. Configuring Airtel SIP alongside Safaricom provides carrier redundancy, if one provider has an outage, calls route via the other automatically.
Telkom Kenya SIP trunks
Telkom Kenya SIP trunking supports landline DDI numbers and PSTN connectivity for businesses that need a traditional landline number format alongside mobile carrier access.
Carrier redundancy configuration
Sentire configures 3CX or your VoIP platform to use primary and failover SIP trunks. If the primary carrier's SIP endpoint is unreachable, outbound calls automatically route via the secondary trunk, maintaining business continuity without manual intervention.
SIP trunk integration is part of Sentire's VoIP communications service, configured alongside VoIP system deployment and 3CX Cloud PBX for businesses needing a complete end-to-end solution.
Are your call costs what they should be?
Most businesses overpay for carrier connectivity because they've never benchmarked SIP against their current analogue or hosted voice arrangement. Sentire will review your current call costs and show you what you'd pay with SIP trunking, before you commit to anything.
