I'm working on a TA 924e. How do I configure an FXS port to auto-answer? I'm running the FXS ports to wall intercoms. However, they're connected to a sip-identity and will be dialed from an IP/SIP phone not connected to the Adtran.
voice trunk T09 type sip
sip-server primary reg.server.com
voice grouped-trunk VOICETRUNK
accept $ cost 0
voice user 1009
connect fxs 0/1
sip-identity xyz T09 register auth-name "xyz" password "abc"
FXS ports cannot auto-answer because the hook switch is on the device that is connected to the port. The only way to auto-answer off an FXS port would be to have a device that will automatically go off hook when it detects ring voltage.
I thought I had seen on a Linksys PAP2T's that you could setup auto-answer which fulfills the same application seen in the configuration posted, however, I verified that it is indeed not possible as adtran support states above.
