Gejala
Di lingkungan terpadu Microsoft Skype for Business Server dan Exchange Server 2016 Unified Messaging (UM), panggilan tak terjawab dari pengguna Microsoft teams ke pengguna Skype for Business lokal akan dibuang dan bukan menggulung ke pesan suara. Selama panggilan terputus, kejadian dicatat dalam log kejadian aplikasi dari UM server Exchange:

Pengecualian ini terjadi di platform VoIP Microsoft Exchange Speech Engine selama operasi asinkron berbasis kejadian yang dikirimkan oleh server. Server akan mencoba memulihkan dari pengecualian ini. Jika peringatan ini sering terjadi, hubungi dukungan produk Microsoft.
Selain itu, Anda menerima pesan kesalahan 500 berikut dalam log SIPstack: Kesalahan server internal SIP/2.0 500 akan ditemukan dalam log SIPstack dengan informasi diagnostik berikut ini:
diagnostik MS: 24014; Component = "RTCC/5.0.0.0_MSExchangeUM/<IP address>"; Reason = "terjadi kesalahan media internal"; Source = "<FQDN dari Exchange UM server>"
Penyebab
Exchange Server 2016 UM menggunakan Unified Communications Managed API (UCMA) 4,0 untuk mengurai informasi protokol sesi (SDP). Namun, Microsoft teams menggunakan parameter MTURNID baru dalam SDP yang diperkenalkan setelah rilis UCMA 4,0.
Pemecahan Masalah
Untuk memperbaiki masalah ini, perbarui UCMA 4,0 ke versi 5.0.8308.1091 untuk Exchange Server 2016 UM dengan menggunakan Penginstal pembaruan kumulatif Lync Server 2013.
