Question 1

A SIP Trunk is a logical connection between an IP PBX and a Service Provider’s application servers that allows voice over IP traffic to be exchanged between the two. When a call is placed from an internal phone to an external number, the PBX sends the necessary information to the SIP Trunk provider who establishes the call to the dialed number and acts as an intermediary for the call. All signaling and voice traffic between the PBX and the provider is exchanged using SIP and RTP protocol packets over the IP network. Which two statements about SIP trunk are true?

A. A SIP trunk configuration is mandatory for a UC500 device.

    I think that an ATA/186 works fine with SCCP protocol ;)

    Nope, voicetut is right:

    Note: Fax pass-through for ATAs attached to Cisco CallManager Express (CME) is presently supported only with the H.323 protocol.

    in Line with Question-4, I was thinking answer should be “SCCP”, after all its Skinny Client Protocol :-) , But realized it is proprietory for Cisco, and Fax is not a CISCO Product, Hence “H323″ seems to be logically correct.
    Other related questions for connecting Fax are, as following.
    Q:- Which of the following devices allows you to convert signals from an analog fax machine into VoIP packets?
    a. Cisco 3911
    b. Cisco 7985G
    c. Cisco ATA
    d. Cisco Expansion Module
    Ans:- c. Cisco ATA
    - – -
    Q:- Which of the following interface types would you use to connect an analog fax machine to the VoIP network?
    a. FXS
    b. FXO
    c. E&M
    d. BRI
    Ans:- a. FXS

    If your interested in Flash Cards you can print yourself… download this pdf and print page one, then flip and print page two. Same goes for every two pages.

    http://rapidshare.com/files/440381971/Questions.pdf

    let me know your thoughts… If it is too difficult to print these pages, then the CCNA Voice is gonna put you through the ringer. I dont have a duplexer, so I am not sure how this works on a duplexer. For me it is a manual print, flip, print.. use Card Stock for durability…

    My wife did this for me testing so if you like please let me know.

    Trick question because cisco analog ATA device is
    not supporting H323 for many years now -
    Only SIP or SCCP (or buy a linksys)

    For instance those with vonage service at home
    you are using analog ATA with voice and / or fax
    line to phone or fax machine – it is SIP
    Communication you have here – not h323

    Here u see SIP support for fax via ATA

    Now it makes it very confusing since both
    H323 and SIP seem to be supported with ATA
    and CME. I go with up to date cisco supported answer which is SIP
