Hello Guys,
I am facing issue implementing the Lync + OXE integration using the Audiocodes SBC over the LAN only (LAN network).
When I trying to call from OXE >= Lync call works well but call from Lync to OXE fails & OXE produces the error (503 services not available).
Setup=
OXE extension: 19011 OXE Domain: sip.corp.arc.com
Lync client: +12345678@corp.arc.com
Please help me to troubleshoot this? I have attached the PBX & SBC traces.
