Hello there. I already deploy CUCM 11.5 Publisher (76.76.76.151) and CUCM 11.5 Subscriber (76.76.76.154). I got my FXO card and PVDM installed on 2900 Router that act as voice gateway (76.76.76.152). I put my telco line on that FXO port 0 which had a PSTN number (This line is active and when i put it in an analog phone, it can be called) I also have my 3905 + 8865 NR IP phone which is already registered on the CUCM. I can make a call locally, DN to DN. But when i tried to call these extension from outside (from my cell phone to be precise), it won't work. Same as when I try to make the outbound call when I hit the pattern (i set this pattern on the route pattern 9[0]XXXXXXXXXXX).    My question is... To make the inbound and outbound call work, what am i missing? Thanks so much for your attention sir. I'm quite new to this voice thing   and here is my show run output on the gateway (76.76.76.152)   VoiceGateway#sho run Building configuration... Current configuration : 2522 bytes ! !
