HI,
Need an expert guy to assist for what the problem i am facing currently.
OXE System (rel11.0.1K1520.47a) and SIP phone model 8012 (rel3.59).
The client complained the SIP Phone always in one way communication (no voice from another side) and SIP always in "sleep mode" status.
1. When Extension A (1001) call to SIP phone ( 1080) 8012 model, Ext 100 can hear the dial tone, and SIP phone (1080) answered the call, but 1001 cannot hear the voice from SIP phone 1080.
2. When Extension A (1001) call to SIP phone ( 1080) 8012 model, Ext 100 can hear the dial tone, but no ringtone from SIP phone (1080). SIP register show sip phone 1080 is active. The user has to reboot or hard reset the sip phone, then only able to call in.
Does anyone have the same issue problem? Seeking your help, thanks
