Hi All,

Hoping for a solution. Your help will be appreciated.

Problem

PJsip client sends SIP requests on the same TCP connection

Setup details

I have pjsip client service which sends request to SIP servers on Google Cloud Platform (GCP) installed on same VPC.
In between these 2 components we are introducing "Internal TCP load balancer". Basically we wanted to load balance the TCP traffic(SIP Messages) from pjsip client to different SIP Servers sitting behind the load balancer as depicted in the diagram below.

Observation

Since the pjsip have single transport created and hence the request goes on the same connection to Load Balancer ip-address. Load balancer balances the traffic based on the rule "Client IP, Src port and protocol".. Since any request coming from PBX1 pjsip client will always be having same ip-address and the connection is also same.. all the requests for going to one SIP Server. Because of this we are not able to load balance the traffic to other SIP Servers

Could any one suggest me how I can create different connections for each SIP session created by same PBX pjsip client (PBX1).

Regards
Naveen.S

Hi All,

I have created an endpoint and starting the transport associating with the same endpoint.

Is there any example of using multiple endpoints and associating transport for each of the endpoints.. so that I can have multiple TCP connections created.

Anyone please give me suggestion for my use case.

Hi Naveen

What load balancer are You using?
I would suggest using Kamailio, it is designed to do SIP load balancing.

Somehow I think that You are lucky that a normal TCP load balancer works.
