No inbound audio on HT-286


#1

I have an HT-286 connected to an analog conference phone. Internal calls between extensions work just fine, but outgoing calls through our SIP trunk provider result in one way audio (outgoing audio is passed through, but incoming audio doesn’t make it to the phone). All other handsets in our office (combo of Snom 320s and Cisco SPA504Gs) work perfectly fine through the SIP trunk.

I wouldn’t think this is a NAT issue since the phones are talking to a server on our local network and shouldn’t be directly communicating through our firewall, unless I’m missing something?

sip.conf (setting is identical for all other handsets):

[Conference]
    disallow=all
    canreinvite=no
    nat=no
    allow=ulaw
    allow=alaw
    callerid="Conference Room" <220>
    secret=MY PASSWORD
    context = internal
    type=friend
    host=dynamic
    subscribecontext=internal

Here’s the sip trace on a failed call (call connects, but I can’t hear callee caller/callee phone numbers replaced with “NUMBER_I_AM_CALLING” and “MY_PHONE_NUMBER”):
