What is SIP?
Session Initiation Protocol.
It is a standard communications protocol used for controlling multimedia communication sessions. For public service outside of your local network, users must register with a VoIP provider which provides a directory service similar to a public switched telephone network for POTS lines.
The AutoHybrid IP2 protocol stack provides the components necessary to provide a standardized method for managing the device, providing real-time multimedia transport and monitoring and controlling the Quality of Service.
SIP is a standard mechanism for connection management, including registration and location service, that provides phone number portability across the internet.

General
Registering
AutoHybrid IP2 replaces your VoIP phone, therefore you must register it with your VoIP service. On the Accounts tab, enter your account information. After you enter ALL of your account information, click <Save> and <Restart SIP Service> for changes to take effect. Your Account information is saved on the AutoHybrid IP2, it will not need to be re-entered unless it is unregistered.
Account Name (ex: Studio1)
This is only used to identify your IP2 in your conguration and system logs. It is
not necessarily required for registering your IP2 with your SIP service/VoIP phone system. Create a friendly name that is easy to read and remember. An example would be a host's name to identify the device as opposed to its IP address.
Display Name (ex: John)
When making peer-to-peer calls, this is how you will be identied to the party
you are calling. When using a SIP service and making a call by dialing a phone number, the number assigned to your account by your SIP service/VoIP phone system may be used to identify you to the party you are calling. Caller ID must be supported/provided by your SIP service/VoIP phone system in order for the party you are calling to see your identifying information. The Display Name may be the same as your Username but should be more accountable if you have a popular username.
Username / Number (ex: J12345)
This information will be provided by your SIP service/VoIP phone system. Enter
the username that is associated with your SIP account. If this eld is left blank, or if you enter the information incorrectly, you may have difculty registering/using
the IP2 with your SIP service/VoIP phone system.
Domain (ex: sip.ringcentral.com)
Enter the domain of your registered SIP account. If registering IP2 with a SIP service, enter the SIP Domain provided by your SIP service. If you are installing the IP2 on your network, and you will not be accessing outside lines, leave this
eld blank. Leaving the Domain eld blank will only allow calls to devices within
the user's network.
Domain Registration
Check this box if you are registered with a domain to be able to receive calls. If unchecked, the account will be started in Peer-to-Peer mode and you will not be
able to call outside of your local area network.
Password
Enter the password provided by your SIP service/VoIP phone system IT administrator.
Accounts
Topology
SIP Transport Mode
There are three SIP Transport Modes: Automatic, TCP, and UDP. Automatic should be selected unless otherwise specied by your SIP service/
VoIP phone system IT administrator.
Local Port
This port number will be provided by your SIP service/VoIP phone system IT administrator. If the wrong port number is entered, you may encounter problems registering or using the IP2 to make or receive calls..
STUN (Session Traversal Utilities for NAT)
STUN usage recommendation and, if necessary, the STUN server name and port assignment (located under Network>Additional Settings) will be provided by your SIP service provider/VoIP phone system IT administrator.
Line Assignment:
The IP2 allows the user to set up two different accounts, Account 1 and Account 2. This box gives the user the option to assign account conguration to either Line 1, Line 2, or Both lines.
QoS (Quality of Service)
The Account Quality of Service (QoS) tab, contains two attributes which dene
the Differentiated Services (DiffServ) Code Point (DSCP) element of the DS
eld of IP packets for RTP and SIP trafc. The default DSCP settings are fairly standard and should only be modied as specied by a network administrator with knowledge of a specic network's QoS implementation.
Advanced
Auth Username
Enter the Authorization ID provided by your SIP service/VoIP phone system IT administrator.
Proxy and Proxy Port
A proxy, or proxy server, is basically another computer which serves as a hub through which internet requests are processed. Enter the proxy address and port number provided by your SIP service/VoIP phone system IT administrator here. Without this information, the IP2 will not know where to send a request to contact another device.
Registration Lifetime
This is the time period (in seconds) for which an account Registration is valid. After expiration of this period, the registration at the service provider for this
Graphic User Interface
9
Accounts
10
account is no longer valid. Re-registration is done automatically. A registration for this account will be sent to the service provider sometime before the last registration is due to expire. Your SIP service provider/VoIP phone system administrator will provide you with instructions on what information, if any, needs to be entered/changed here.
Keep-Alive
Enables sending periodic keep-alive data to the SIP server to ensure that the communication channel remains open. When the AutoHybrid IP2 is behind a router running network address translation (NAT), this prevents the NAT from closing the channel prematurely. Your network system administrator will determine if this box needs to be checked.
Silence Suppression
This is a method for reducing the average bandwidth used by the audio. It is useful in instances where long durations of silence are expected/encountered. Your SIP service provider/VoIP phone system IT administrator will determine if this box needs to be checked.
Account Status
An account is ready to make or receive calls if the Account Status is Peer to Peer Registered or Proxy Regsitered. If the Account Status is Proxy Registering,
Congured, Conguring, Not Congured or Unknown, the account is not ready and may have a conguration error.
Account Error
If a registration error is detected or reported by the service provider, an Account Error will be displayed. If the Account Error is Proxy Error or Proxy Timeout, there
may be an error in the Username, Domain, Proxy or Proxy Port conguration.
If the Account Error is Authentication Failure or Register Failure, there may be
an error in the Username, Auth Username or Password conguration. If the
Account Error is Proxy Error, there may be an error in the Proxy or Proxy Port
conguration.
Codec Preferences
Waveform based codecs quantize the actual waveform. Speech based codecs use a model of speech production for better compression. Waveform based codecs generally work better.
Select the desired codec/s from the list of codecs available and click <Enable> to move it to the preferred list. When there is more than 1 preferred codec, the <Move Up> and <Move Down> buttons set priority for which codec is used.
The preferred codecs list is saved on the AutoHybrid IP2, therefore users will not have to reselect their preferred codecs for each use. Users can save and
store multiple proles on their computer for different applications that might require different codecs. Users will be able to backup/download proles and restore/upload their congurations from the Management tab.

FAQs
1. I am receiving error message: NOT ACCEPTED HERE
When both end-points do not share a preferred codec, the call might fail. If there's a compatibility issue between the two end-points, error message: Not Accepted Here will be displayed. This means that the two end-points could not agree on a codec. To resolve this issue, make sure the two end-points have a few codecs in common.
2. I changed my network settings and now I can not connect to the AutoHybrid IP2.
Perform a Network Reset found on page 15 to reset your device to the default Dyniamic IP setting. See page 5 to nd the Dynamic IP address.
3. I have lost my power supply for my AutoHybrid IP2.
I have a power supply that ts from a different product. Can I use this instead?
No! Never use a power supply other than the one that was supplied by your manufacturer. Power supplies are available in either AC or DC output with many combinations of voltage and available current. Most consumer power supplies are not regulated. This could invariably damage your equipment, and also create a great deal of noise. Our products are designed for and tested with their respective power supplies for optimum operation. If you have lost your power supply, please contact your JK Audio dealer or our Customer
Service department.
AutoHybrid can also run using PoE power, supplied over the ethernet cable from a PoE equipped switch or router.
4. Will the USB port on the AutoHybrid IP2 act as a sound card when connected to a computer?
No. The USB port is not designed to exchange audio between the AutoHybrid IP2 and your computer.
