What SIP Access includes

SIP trunking, with the infrastructure around it already built.

Signals SIP Access provides the SIP origination and termination you expect from a trunking service. It also gives your technical and operations teams the numbers, visibility, account controls and infrastructure support required to run production call traffic.

Conventional SIP trunking may provide

  • Inbound and outbound SIP connectivity.
  • The provider’s available number inventory.
  • Call-detail records and usage reports.
  • A provider-specific account and support process.

Signals SIP Access adds

  • Familiar Nigerian mobile numbers.
  • Numbers from multiple providers managed in one account.
  • Control over the originating number used for outbound calls.
  • Transparent call records, usage and billing.
  • Real-time network-performance visibility.
  • Programmable Voice and Automations on the same platform.

How it works

From SIP trunk provisioning to production traffic.

  1. 01Review your architecture and workload with the Signals team.
  2. 02Confirm platform compatibility, traffic profile, numbering and commercials.
  3. 03Complete the account and KYC requirements for your organisation.
  4. 04Signals provisions the SIP trunk, credentials, numbers and routing.
  5. 05Your technical team configures your contact-centre, PBX or voice system.
  6. 06Run joint testing on controlled traffic with Signals.
  7. 07Activate production traffic.
  8. 08Monitor calls, usage and network performance, then expand.

Signals SIP Access is managed SIP trunking delivered as a provisioned infrastructure service. Signals provisions the SIP trunk, credentials, numbers and routing for your workload after technical discovery and qualification.

Your technical team then configures your own contact-centre platform, PBX, dialler or voice application against that provisioned infrastructure. We test the connection together before production traffic is activated.

Technical discovery is the normal starting point for a SIP workload.

Capabilities

The managed telephony layer underneath your existing voice system.

SIP origination and termination

Send and receive supported call traffic between your voice platform and the telephone network.

Familiar Nigerian mobile numbers

Call from numbers customers recognise, instead of asking staff to use personal lines.

Multi-provider number access

Purchase numbers supplied by different Nigerian providers and manage them in one account.

Originating-number control

Choose which number you own is used for an outbound call.

Call and usage visibility

Review call logs, usage and recordings for the traffic running through your account.

Quality-managed access

Signals monitors customer access and prohibited traffic to protect number reputation and network quality.

Operating visibility

See the infrastructure your calls are running on.

Call logs are transparent and network performance is visible in real time while your workload is running, so operations teams can see what is happening rather than infer it later.

Enterprise assurance

Capacity, recording and hosting your reviewers can verify.

Operated on certified, locally hosted infrastructure.

Current platform capacity is 5 million calls per day, and channel, concurrency and recording capacity are provisioned to your expected traffic. Enterprise agreements support configurable multi-year retention, active and archival storage with defined retrieval SLAs, and export through API or dashboard before scheduled deletion.

Operating Model

Your trunk is operated, not merely provisioned.

Signals SIP Access includes controlled activation, proactive service monitoring, defined critical-incident escalation and capacity planning around the production workload.

  • Architecture and connectivity review
  • Controlled migration and cutover
  • Named technical ownership
  • 24/7 response for critical incidents
  • Post-launch hypercare

Where an incident involves an upstream network provider, Signals coordinates the investigation and remains responsible for customer communication through the service path.

Onboarding

Provisioned by Signals. Configured by your technical team.

Standard SIP provisioning is the normal service and carries no additional fee. It covers the architecture and workload review, trunk setup, credentials, number routing, test support and production activation.

The ₦500,000 per year Base plan subscription may be required commercially, but subscribing does not automatically provision or activate a SIP trunk. SIP Access requires technical approval and infrastructure provisioning by Signals.

Optional assisted implementation, where Signals goes further and helps configure, migrate or integrate your own environment, requires either a contractual ₦500,000 monthly call-usage commitment or a ₦1.5 million one-time fee.
