Integration Steps

Access Your PBX/Phone System Settings: Log into your PBX/Phone system admin portal. Navigate to the settings or configuration section.

Locate SIP/VoIP Settings: Look for SIP or VoIP settings within your PBX/Phone system interface. Find options related to trunking, SIP configuration, or VoIP integration.

Create SIP or Add your PBX IP:

  • Adding IP Address: https://docs.didforsale.com/sip-trunking/sip-trunking/ip-configuration

  • Creating SIP Account: https://docs.didforsale.com/sip-trunking/sip-trunking/sip-account

Configure SIP/VoIP Settings: Input the SIP credentials provided by DIDForSale. These typically include SIP server address, username, password, and authentication details. Ensure that codecs (g711, ulaw & alaw) and other audio settings align with our recommended configurations.

Network Configuration: Check firewall and network settings to ensure traffic from our service is allowed. Whitelist our server IP addresses if your system has security features. Get a list of our IPs here:

Configuration of DID number: Follow the link for instructions:

Testing and Verification: Make test calls to confirm the integration. Test both incoming and outgoing calls for quality and reliability. Test additional features like voicemail, call forwarding and conference calls. Contacting Support:
