SIP-to-SIP Call Transfer
Overview
Our platform supports SIP-to-SIP call transfers, enabling users to transfer an active call to a specified SIP address instead of a traditional phone number. This feature enhances flexibility by allowing direct transfers within SIP networks without relying on phone numbers.
How to Use SIP-to-SIP Transfer
When transferring a call, instead of entering a standard phone number, you can provide the SIP address in the "Transfer the call to" field. The SIP address should be in the following format:
sip:username@domain:port
Example SIP Address Format
Here is an example of a valid SIP address you can use to transfer a call:
sip:[email protected]:5060
sip:
: The protocol identifier for SIP.+19495935555
: The user part, which could be a phone number, a username, or other SIP identifier.@208.128.12.100
: The domain or IP address of the destination SIP server.:5060
: The port number (default SIP port is 5060).
Step-by-Step Transfer Instructions
-
Initiate a Transfer:
-
During an active call, navigate to the "Transfer the call to" section or field.
-
-
Enter the SIP Address:
- Instead of entering a phone number, type the target SIP address in the format:
sip:username@domain:port
- Example:
sip:[email protected]:5060
- Instead of entering a phone number, type the target SIP address in the format:
-
Complete the Transfer:
- Confirm the transfer by pressing the appropriate button or completing the action in your system's user interface.
Important Notes
- Ensure the SIP address is correctly formatted with the appropriate protocol (
sip:
), username, domain, and port. - Verify that the SIP server (specified by the domain or IP address) is reachable and configured to accept incoming SIP requests from your system.
- If the first part of SIP address is a phone number, ensure its prefix with country code (ie.
+1
) - If no port is specified, the default SIP port
5060
is used.
Benefits of SIP-to-SIP Transfer
- Direct Routing: Enables calls to be transferred directly within SIP networks, bypassing the need for traditional telephony infrastructure.
- Network Flexibility: Transfers can be made to any reachable SIP address, supporting a wide range of devices and endpoints within a SIP network.
- Improved Efficiency: Reduces dependency on public telephone networks, leading to cost savings and more efficient call routing.
Troubleshooting
- If the transfer fails, check for the following:
- SIP Address Accuracy: Verify that the SIP address is entered correctly.
- Network Connectivity: Ensure that there is proper network connectivity between your system and the destination SIP server.
- SIP Server Configuration: Confirm that the destination SIP server is configured to accept SIP transfers from your domain or IP address.
