SIP TRUNKINGFOR BUSINESS
SIP trunks replace traditional phone lines with internet-based voice connections. Each trunk carries multiple simultaneous calls, reducing line costs while maintaining your existing phone system and numbers.
Why SIP Trunking

SIP trunks cost significantly less than PRI lines or individual analog lines. Pay only for the channels you need.
Keep Your PBX
Add SIP trunks to your existing phone system without replacing hardware. Start saving on line costs immediately.
Scalable Capacity
Add or remove channels in minutes. Scale call capacity up for busy seasons and down when volume drops.
Geographic Flexibility
Get local phone numbers in any area code without physical presence. Support remote offices and distributed teams.
SIP Trunking Questions
What is a SIP trunk?
A virtual phone line that delivers voice calls over your internet connection instead of traditional copper phone lines. Each SIP trunk can carry multiple simultaneous calls.
Can we keep our existing phone numbers?
Yes. PTG handles number porting from your current carrier to SIP trunks. The process typically takes one to two weeks with zero disruption.
Do SIP trunks work with any PBX?
Most modern PBX systems support SIP trunking. Older systems may need a VoIP gateway to connect. PTG evaluates compatibility during assessment.
How many SIP trunks do we need?
PTG analyzes your peak concurrent call volume and recommends the right number of channels. A general rule is one channel per three to five employees.
