Cloud Contact Center supports SIP Trunk integration with enterprise numbers, enabling the use of the enterprise's own numbers for incoming and outgoing calls. After the integration, the enterprise independently settles the communication costs incurred by the number with the originating ISP. Tencent Cloud Contact Center does not charge for integration or communication costs. This document will demonstrate the number integration SIP process.
The process includes two steps:
1. Create a SIP channel and configure the SIP device/SIP trunk.
2. Add numbers within the SIP channel.
Step 1: Create a SIP Channel and Configure the SIP Device/SIP Trunk
1. Go to the configuration page for your own numbers
Currently, Landline numbers are supported for integration. Please directly click Next.
2. Create a SIP Channel
2.1 First, name your channel
2.2 Choose an access method
Cloud Contact Center provides four connection modes:
Public network SIP trunk docking (Domain Name Integration)
Public network SIP trunk docking (IP Allowlist Integration)
Cloud Contact Center provides a SIP account
The line ISP provides a SIP registration account
Public network SIP trunk docking (Domain Name Integration)
Public network SIP trunk docking (IP Interconnection)
The line ISP provides a SIP registration account
Cloud Contact Center provides a SIP account
This method is suitable for when you purchase a number from ISPs like Twilio, Vonage, etc., and fill in the ISP-provided address into the Cloud Contact Center platform.
I. Outbound call configuration
1. Domain name and port
Domain name: Cloud Contact Center overseas data centers are independently deployed in Singapore. You can refer to the ISP documentation to select nodes near Singapore.
Port: Typically defaults to 5060.
2. Account authentication
In the Authentication information field, enter the ISP's authentication information.
Account: Please refer to the ISP platform.
Password: Please refer to the ISP platform.
II. Outbound call configuration
After completing the entry, please click Create.
This method is suitable for docking with the enterprise line ISP through the SIP trunk of the Internet.
1. Fill in the SIP address
Fill in the public IP address for your SIP device or ISP's SIP trunk to receive SIP signaling. (The default port for SIP UDP is 5060. Confirm whether the IP address you filled in is a SIP address.)
You can find the SIP gateway IP address and SIP UDP port in the background of your gateway, for example:
2. Authorize Tencent Cloud to access the IP
Add the following addresses to the allowlist of the SIP device/SIP trunk to authorize Tencent Cloud to access your SIP device or ISP's SIP trunk.
Copy the above addresses and add them to the allowlist, for example:
3. Configure the Tencent Cloud SIP address for your SIP device or ISP's SIP trunk to send signaling to Tencent Cloud's address.
This method is fit for enterprise lines ISP provided SIP registration accounts. The cloud call center registers with the line ISP through SIP accounts and configures the SIP account information provided by the ISP into the gateway.
This method is applicable when an enterprise-owned gateway device or IPPBX is connected to Cloud Contact Center.
Click Create Channel and configure the gateway information of the channel into your gateway.
1. The following figure shows the SIP account information of the channel created by Tencent Cloud.
2. Configure your gateway.
2.1 Configure the SIP server
2.2 Configure the port O.
2.3 Add the call and routing policies.
Step 2: Add numbers
1. When the SIP channel is successfully created, please click Add Number under your channel.
2. Add numbers.
Select the application of using your own number, configure prefix for sending numbers, and add your number (please enter the number with area code in the number details).
Note:
International numbers typically use the +E.164 format, i.e., [+][country code][number] (e.g., +86123456789). Some ISPs use E.164 (i.e., without the plus sign). It is recommended that you confirm the sending number format with the ISP when filling out the information
Click Submit for Review. After approval, you can manage numbers under the numbers that have taken effect.
