My phone registred and running

#sh ephone registered

ephone-3 Mac:0017.E072.EBF3 TCP socket:[1] activeLine:0 REGISTERED in SCCP ver 5 and Server in ver 5

mediaActive:0 offhook:0 ringing:0 reset:0 reset_sent:0 paging 0 debug:1 caps:6

IP:192.168.2.219 1044 7920   keepalive 789 max_line 6

button 1: dn 2  number 1001 CH1 cc(03)   IDLE

But when I call to FXO port from outside, FXO forward my call to cisco 7920 ephone, In this moment I see this:

#sh ephone registered

ephone-3 Mac:0017.E072.EBF3 TCP socket:[1] activeLine:0 REGISTERED in SCCP ver 5 and Server in ver 5

mediaActive:0 offhook:0 ringing:1 reset:0 reset_sent:0 paging 0 debug:1 caps:6

IP:192.168.2.219 1044 7920   keepalive 783 max_line 6

button 1: dn 2  number 1001 CH1 cc(03)   RINGING

call ringing on line 1

line 1 ref 61 state 4

and this

#show voice call status

CallID     CID  ccVdb      Port             DSP/Ch  Called #   Codec    Dial-peers

0x7D       131C 0x85B77660 2/0                      1001       None      289/20002

0x7E       131C 0x85B4650C 50/0/2.0                *1001       None      20002/289

BUT IP Phone does not RINGING, after about 30 sec it starts RINGING.

Help me please understand why this delay so long?

I have this problem too.

What Access Point are you using? Do you have voice and data VLAN in your wireless network? and have you done any QoS configuration at the AP level?

You was right, when I change my TRENDnet AP to Cisco 1130 AP, problem gone away
