SIP Trunking Frequently Asked Questions (FAQs)

What is SIP Trunking and how does it work?

SIP Trunking is a service that allows businesses to make and receive phone calls over an internet connection instead of traditional phone lines. The entity “SIP Trunk” connects your existing IP-PBX (Internet Protocol Private Branch Exchange) to the Public Switched Telephone Network (PSTN) via a SIP trunk provider. It uses the Session Initiation Protocol (SIP) to manage call setup, teardown, and media (voice) transmission for VoIP calls. This typically reduces costs by up to 60% and offers greater flexibility.

What are the main benefits of SIP Trunking over PRI or traditional lines?

The primary benefits of SIP Trunking compared to PRI (Primary Rate Interface) or analog lines include: 1. Significant Cost Savings: Lower monthly line rental fees, reduced call rates (especially for international calls), and elimination of expensive PRI hardware. 2. Scalability: Easily add or remove SIP trunk channels (concurrent calls) in minutes, unlike the fixed capacity of PRI. 3. Flexibility: Consolidate voice and data on one network, support remote workers, and enable multi-site connectivity with ease. 4. Enhanced Features: Access to modern VoIP call features like HD voice, number portability, and disaster recovery options. Many businesses see a SIP trunk vs PRI cost reduction of 40-70%.

How many SIP trunk channels does my business need?

The number of SIP trunk channels needed depends on your peak concurrent call volume. A general rule of thumb for many businesses is 1 channel for every 3-4 employees. However, call centers or businesses with high inbound/outbound call traffic might require a higher ratio. RockyDialer can help analyze your current call traffic (e.g., from your existing PRI lines) and recommend the optimal number of SIP channels per trunk to ensure quality service without overprovisioning, thereby optimizing your SIP trunk cost.

Is SIP Trunking reliable and secure for business communications?

Yes, when sourced from reputable SIP trunk providers like RockyDialer, SIP Trunking is highly reliable and secure. We offer carrier-grade reliability with 99.99% uptime SLAs, achieved through redundant network infrastructure and partnerships with multiple Tier-1 carriers. For security, we support TLS for signaling encryption and SRTP for media (voice) encryption, alongside IP authentication and fraud detection systems. This ensures your business phone system communications are both consistently available and protected.

Can I use my existing PBX system with RockyDialer's SIP Trunks?

Yes, in most cases. RockyDialer’s SIP Trunks are designed to be compatible with nearly all IP-PBX systems that support the SIP protocol.
