CallTower Cloud SIP-FIRST
SIP-First Approach for Voice Migration to the Cloud: Streamlining the Transition
Introduction
As businesses embrace digital transformation, migrating Unified Communications (UC) systems to the cloud becomes essential. However, challenges such as porting Direct Inward Dialing (DID) numbers and integrating on-premise systems with cloud platforms can complicate the process. CallTower’s migration experts have developed solutions, including the SIP-First approach and the Crawl-Walk-Run-Fly strategy, to simplify the transition and ensure a controlled, predictable rollout.
The SIP-First Approach
The SIP-First approach is a phased strategy that begins with establishing a Session Initiation Protocol (SIP) connexion to CallTower. This step precedes any DID porting or cloud migration, ensuring a seamless transition.
Technical Process
- Establishing SIP Connection:
- Set up a CallTower SIP trunk that mirrors the existing on-premise UC PSTN service.
- Acts as a bridge between the on-premise system and CallTower’s cloud environment.
- Porting DIDs to SIP Trunk:
- Once the SIP connexion is tested, DIDs are ported to the trunk.
- This step transfers control of the DIDs to CallTower while keeping them operational on the existing system.
- Transition to Cloud UC:
- Redirect DIDs to the selected cloud UC platform (e.g., Cisco Webex, Microsoft Teams, Zoom).
- Strategically plan the transition to minimise disruption.
- Consolidate DIDs on CallTower’s network for streamlined management.
Benefits
- Minimized Disruption:
- Separates DID porting from the cloud platform rollout, ensuring continuity of business communications.
- End users remain unaffected by porting issues.
- Flexibility in Migration:
- Schedule the final migration to the cloud platform at a convenient time.
- Reduces the risk of unplanned downtime.
- Enhanced Control and Testing:
- Test the cloud UC platform with actual DIDs in a controlled environment before going live.
- Risk Mitigation:
- Identify and address porting issues without impacting overall UC functionality.
- Streamlined Change Management:
- Provides time for staff training and adaptation to the new system.
Conclusion
CallTower’s SIP-First approach simplifies the complexities of migrating from on-premise to cloud UC systems. By separating DID porting from the platform rollout, businesses can ensure a smoother transition with minimal operational impact. This strategy enhances efficiency, mitigates risks, and positions IT teams as key contributors to successful cloud migration.
As businesses increasingly adopt cloud solutions, CallTower’s SIP-First approach stands out as a reliable and effective strategy for Unified Communications migration.
