Eliminate a SIP proxy between a BYOC Premises Edge and a SIP provider
AI-generated summary
Genesys Cloud enables direct connection from a BYOC Premises Edge to a SIP provider without a SIP proxy if the SIP provider can sequentially distribute calls to multiple IP addresses and has enough physical ports for each Edge. The steps are to confirm the SIP provider meets those capabilities, physically connect each Edge to the SIP provider using one port per Edge, configure an IP address on each Edge, provide the SIP provider a list of IP addresses to sequentially roll calls across. A SIP proxy is required if the SIP provider cannot sequentially distribute calls across multiple IP addresses or lacks sufficient physical ports per Edge.
Based on the capabilities of the SIP provider, a BYOC Premises Edge requires or does not require a SIP proxy between a premises-based Edge and a SIP provider.
No SIP proxy required
A premises-based Edge does not require a SIP Proxy if the SIP provider meets both of the following requirements:
A SIP provider can sequentially roll calls, load balance, or percentage allocate between a list of IP address endpoints supplied by the customer.
A SIP provider has enough individual physical network interface ports on the SIP carrier device to have a physical port available for each Edge device.
For inbound calls, the carrier distributes calls among the Edges. For outbound calls, Edges load balance with randomization.
Note: Multiple premises-based Edges can process calls at the same time. You should not route calls to a single Edges but distribute the calls among multiple Edges.
Steps for direct connection without a SIP proxy
Determine that the SIP provider can sequentially roll calls through a list of IP addresses.
Determine that the SIP provider has enough individual physical network interface ports on the SIP carrier device to have a physical port available for each Edge.
Physically connect a single port to a single Edge for all Edges.
Provide a list of your configured IP addresses to the SIP provider and request that the SIP provider sequentially roll inbound calls through those IP addresses.
SIP proxy required
An Edge requires a SIP Proxy for either of the below situations:
A SIP provider cannot sequentially roll calls through a list of IP addresses supplied by the customer.
A SIP provider does not have enough individual physical network interface ports on the SIP carrier device to have a physical port available for each Edge.
Note: A possible workaround to a lack of available ports is to implement a switch or VLAN tagging solution.
