Hello,
currently, there are no plans to perform interoperability testing with MetaSwitch products, as we don't have any in-house. We do actively perform interoperability testing with Service Providers SIP solutions/offerings; if one of the SP's we plan to test with use MetaSwitch, we will then undertake interop testing to validate MetaSwitch integration capabilities with our products.
