Sprout

This repository contains the core Clearwater SIP function, specifically

  • sprout, the Clearwater SIP router
  • bono, the Clearwater SIP edge proxy
  • restund, the STUN/TURN server used by Clearwater
  • sipp, a SIP stress tool used for testing Clearwater.

Project Clearwater is an open-source IMS core, developed by Metaswitch Networks and released under the GNU GPLv3. You can find more information about it on our website or in our docs.

Sprout and Bono

Sprout is Clearwater's SIP router. It provides most of Clearwater's S-CSCF function. It generally acts as a stateful SIP proxy. It provides registrar function, storing registration information in a memcached store distributed across all sprout instances. It also provides application server function, retrieving Initial Filter Criteria documents from Homestead and acting on them. As well as supporting external application servers, sprout has built-in support for MMTEL services.

Bono is Clearwater's edge proxy. It provides limited P-CSCF function and the some of Clearwater's S-CSCF function. It generally acts as a stateful SIP proxy, receiving SIP messages from users, checking their authenticity and forwarding them to other bono instances or one of the sprout instances.

Sprout and bono share a lot of function and are in fact the same binary, just started with different command-line arguments. They are written in C++, using PJSIP as a SIP stack, curl as an HTTP client, and a selection of other open-source components.

Restund

Clearwater's fork of restund is very similar to the original. The only difference is that the Clearwater fork communicates with Homestead to retrieve SIP digest credentials, which are used to authenticate TURN flows.

SIPp

Clearwater uses SIPp for stress testing. The Clearwater version features improved TCP scalability and also comes packaged with scripts for simulating Clearwater call load and analyzing/reporting the results.
