I can call this number, voice, ... all seems ok. HOWEVER, I cannot call from Xten. What ever I dial, ... there is nothing to see on CLI> Xten setup: Sip Proxy Disabled Default Enabled Proxy1 instead Setings in Proxy 1 Enabled: yes Username: 223344 Authorization User: 223344 Password:**** Domain/Realm: vpbx.elmit.com Sip Proxy: vpbx.elmit.com Out Bound Proxy Use Outbound Proxy: Default (rest default)
