FAQS
Do I need a special phone system for SIP trunking?

Who sells SIP trunks?
SIP trunks are sold by a variety of companies, ranging from established telecom providers like Verizon and AT&T to business VoIP specialists like Nextiva and Avoxi. These specialists focus entirely on providing SIP trunking and other internet-based phone solutions, allowing them to cater specifically to the needs of businesses looking to make the switch from traditional phone lines.
How do I choose a SIP provider?
Focus on finding a reputable SIP provider that offers a plan that aligns with your budget and call needs. Research different providers, compare features and international rates, and choose the one that best complements your business communication goals.
How many calls can 1 SIP trunk handle?
Each SIP trunk handles one call at a time, and you can purchase more channels as your business needs grow. However, the unlimited limit on call volume is your internet bandwidth, as each call uses bandwidth and too many calls can lead to quality issues.
