Team tasked with moving an existing monolithic SIP application to the cloud. Plan is to separate the application from its proprietary SIP stack. One option is to containerize the SIP application. Located a RestComm SIP stack container that seems could be used to replace the proprietary SIP stack. The design team would then develop a container image for the SIP application to communicate with the SIP stack container. My question is, in a host environment in which multiple containers are deployed can the host environment be setup such that the SIP container can receive external SIP messages and communicate internally with the SIP container application (and vice versa) ? If so, is there an example of how this is done ?
