SIP Trunking Solutions for Philippines Businesses
Modernize your communication infrastructure with flexible, cost-effective, and scalable voice connectivity.
What is SIP Trunking?
Session Initiation Protocol (SIP) trunks are telephone line trunks delivered over IP using the SIP protocol
Modern Telephony Solution
Unlike traditional phone lines, SIP Trunks connect IP-PBX or SIP-compatible devices over the internet, providing a logical connection between an IP PBX and VoIP servers.
This allows voice over IP traffic to be exchanged seamlessly between systems, enabling businesses to make and receive calls over internet connections rather than traditional phone lines.
When a call is placed to an external number, your PBX sends the necessary information to the SIP Trunk provider, which establishes the connection to the dialed number using SIP and RTP protocol packets over the IP network.
Key Components:
- SIP Protocol: Establishes, maintains, and terminates calls
- RTP Protocol: Handles the actual voice data transmission
- IP-PBX: Your business phone system
- SIP Trunk Provider: Connects your system to the PSTN
SIP Trunking Technology Flow
Voice calls travel over internet instead of traditional phone lines
