Traffic profile
Estimate inbound and outbound minutes, peak concurrent calls, destinations, working hours and growth expectations.
SIP trunking and route planning
Plan SIP capacity, carrier routes and failover before launch.
Connect a PBX or call center to suitable voice routes with clearer assumptions for concurrent calls, number migration, security, quality and recovery.

Capacity first
A SIP trunk is more than a per-minute rate.
Carrier choice should consider destination coverage, number support, codec compatibility, concurrent calls, support, compliance and route quality. The cheapest headline rate may not be the best operational choice.
Carrier and route fit
Review numbering, portability, CLI requirements, codecs, regional restrictions, emergency calling and support boundaries.
Implementation plan
Define authentication, IP allowlists, routing rules, test cases, cutover, monitoring and a fallback destination.
Routing and protection
Control how calls enter, leave and recover.
The final design can use one carrier or multiple routes. Redundancy only helps when the failure path is tested and operational ownership is clear.
Inbound numbers
Map DIDs to tenants, departments, IVRs or queues and document number ownership and portability.
Outbound policy
Apply destination rules, caller ID policy, route priorities and agreed restrictions for users or tenants.
Security controls
Use strong credentials, network restrictions, spend controls, logs and alerting to reduce avoidable fraud exposure.
Failover behaviour
Plan alternate carriers, number forwarding or recovery destinations and test what happens during a real outage.
Pricing inputs
What changes SIP trunk cost?
Accurate pricing requires a live carrier quote. Bitkrakens can help structure the requirement and compare the operational fit, but published planning figures should not be treated as a guaranteed carrier offer.
Recurring cost factors
- Countries and destination mix
- Inbound numbers and number types
- Concurrent-call or channel requirements
- Expected monthly volume and billing increments
- Support, compliance and emergency service requirements
Deployment cost factors
- Existing PBX and current carrier condition
- Number porting and cutover coordination
- Routing, caller ID and tenant complexity
- Firewall, SBC or SIP edge configuration
- Testing, documentation and monitoring scope
Common questions
SIP trunking FAQ
How many channels do we need?
It depends on peak concurrent calls rather than total user count alone. Historical call records are the best input. Where records are unavailable, the estimate should be conservative and reviewed after launch.
Can we keep our existing phone numbers?
It may be possible through number portability or forwarding, depending on the country, number type, current provider and account ownership. Porting should be confirmed before a migration date is promised.
Can we use our own carrier?
Yes, when the carrier supports the required platform, countries, authentication and operational model. Bitkrakens can work with a bring-your-own-trunk approach or help define a carrier comparison brief.
Does a second carrier guarantee high availability?
No. Redundancy also requires working routing rules, reachable infrastructure, current credentials, monitoring and tested recovery procedures. A second carrier is only one part of the design.
Turn carrier quotes into a clear routing and cutover plan.
