Unable to get SIP phones connected

We have a Centos 6.5 VPS running FreePBX. I’m brand new to FreePBX so please mind my learning curve :smile:

We have a trunk setup with a sip provider which forwards all calls to our FreePBX server. I also have an incoming route setup with a sip number which also works. I am able to make an incoming call and it is registered by Asterisk (I am able to get the ivr prompt). I then have 2 extensions setup (201, 202) and for each of these I have a Yealink W54P phone setup locally. The Yealink base has 2 accounts each registered to 201,202 above. I am able to make a phonecall outbound from the Yealink phones through my trunk. I am just not able to get incoming calls directed to the extensions. My current setup has incoming calls coming into our IVR messaging and via user keypress will then forward the call to the appropriate extension. The calls are immediately directed to voicemail.

Trunk Settings:


Asterisk output when we register the base accounts:

Connected to Asterisk 13.5.0 currently running on voice (pid = 1890)

I hope the above will be suffice. Thank you!
