  • Not Supported

### Basic SIP Configuration

  • Codecs: Our SIP trunk supports two audio codecs – G711A, G711U and Opus. Codecs determine how voice communication is encoded and transmitted.
  • Dial Pattern: We accommodate the dialed format of Country Code + Area Code + Phone Number (e.g., 8498765432, 16505300061) to facilitate easy and standardized calling.
  • SIP Protocol: Our system supports TLS version 1.2 or newer, ensuring the highest level of security for your data exchange.
  • SIP Registration Period: We offer a SIP registration period of 3600 seconds, allowing your devices to maintain a consistent connection.
  • Audio Format: Our SIP trunk supports Secure Real-time Transport Protocol (SRTP) for audio transmission, ensuring the confidentiality and integrity of voice data.
  • DTMF Mode: Our system supports DTMF (Dual-Tone Multi-Frequency) signaling using the RFC2833 standard, allowing the transmission of touch-tone signals during a call.

### Firewall Configuration

Firewall Configuration: To ensure optimal call quality and avoid unforeseen potential issues, it's crucial for customers to whitelist our IP addresses. By whitelisting the specific IP addresses provided here, you're enabling seamless and secure communication through our SIP trunk.

  • Signaling (SIP):
    • IP Addresses: Our SIP server's IP address is 52.77.0.62, and it exclusively supports TLS encryption, guaranteeing secure data transmission.
    • Ports: We utilize port 5061 (TLS with PCMA codec) and port 5081 (TLS with Opus codec) for signaling purposes, ensuring reliable and encrypted communication channels.
    • Direction: Both incoming and outgoing traffic are facilitated through these ports.
  • Audio (RTP):
    • IP Addresses: The IP addresses for audio transmission range from 54.251.255.196 to 54.251.255.211.
    • Ports: The audio transmission ports span from 10000 to 30000.
    • Direction: Both incoming and outgoing audio traffic utilize these specified IP addresses and ports.

### NAT Configuration

NAT Configuration is Optional, recommended for PBX behind NAT:

  • NAT Traversal: We offer support for STUN (Session Traversal Utilities for NAT) to effectively navigate NAT barriers.
  • STUN Server: For seamless NAT traversal, our recommended STUN server is stun.b3networks.com.
