FXS auto-answer configuration

[andrew-jive]

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.

Current config:

voice dial-plan 6 local 1006

!

!

voice trunk T09 type sip

  sip-server primary reg.server.com

!

!

voice grouped-trunk VOICETRUNK

  no description

  trunk T09

  accept $ cost 0

!

!

voice user 1009

  connect fxs 0/1

  password "1234"

  sip-identity xyz T09 register auth-name "xyz" password "abc"

Adtran support:

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.

Thanks!
