Hi Sblazer614,
General configuration guide can be found in the following link, within section 4.

I will mention the main steps to set up the SIP trunk. For complete details please look the above mentioned document.
(Information here is actually taken from that document)
Use the Configuration à Ports and Trunks à SIP/BRI Trunks page to enter the
settings for the SIP providers and BRI gateways that provide Voice over IP (VoIP)
services. You can add up to four different services.
Adding and Removing SIP/BRI Trunks
• Add a SIP/BRI Trunk: Click this button to add a new SIP/BRI trunk.
• Provider: Choose the type of trunk.
• After choosing a provider, either complete all required fields or delete the
record. An incomplete entry produces an error, indicated by a red X in the
navigation tree.
• To remove a SIP/BRI trunk: Click the delete button (X) for the trunk that you
want to remove.
• To enter a list of phone numbers for a SIP/BRI trunk: See the Inbound Calls
page.
SIP Provider Settings
This section is available after you select a provider. To enter the settings, click
Settings. To hide the settings, click the button again. The required fields are
indicated by icons next to the field names. However, your service provider may
require other settings that are not marked in this manner. Be sure to enter all of the
information from your provider.
• Description: Enter a short description of this service for your reference.
• Proxy: Enter the IP address or domain name of the SIP proxy server.
• Require registration: Check the box if the SIP proxy server requires SIP
registration.
• Outbound Proxy: If your provider specified a proxy for outbound calls,
enter the IP address of the outbound proxy server.
• Call Capacity: Select the maximum number of concurrent calls that are
supported on this trunk by your service provider.
• Prefix dialed numbers with: Check the box if this feature is required by the
SIP provider. When this feature is enabled, the system automatically inserts
the appropriate dialing prefix to an external number (such as +1 in the US or
+44 in the UK, based on the specified Regional Settings).
• Company Name: Enter the business name.
• Account ID (often Account Phone Number): Enter the account ID, which is
usually the main phone number for the trunk.
• SIP Domain Name: Enter the SIP domain name, if specified by your
provider.
• Authentication ID: If your provider requires SIP authentication, enter the
authentication code for your account. Typically this code is case sensitive.
• Password: If your provider requires SIP authentication, enter the password
for your account. Typically this password is case sensitive.
• SRV Record Lookup: If required by your provider, check this box to use
DNS SRV lookup for Proxy and Outbound Proxy, or leave this box
unchecked to disable SRV lookup.
• SRV Auto Prefix: If you enabled SRV Record Lookup, you can check this
box to automatically prepend the Proxy or Outbound Proxy name with
_sip._udp when performing a DNS SRV lookup on that name. Uncheck the
box not to use this service.
• Local SIP Port: Displays the local port number that is used for this service.
This information is for your reference, if needed.
• NAT Mapping: Check this box if NAT mapping is not provided by your SIP
provider and therefore local NAT mapping is required. Then specify the NAT
settings in the Systemwide SIP Parameters section. Note: Network
Address Translation (NAT) is a function that allows multiple devices on a
private network to share the same public, routable, IP address to establish
Internet connections. To enable VoIP to co-exist with NAT, some form of NAT
traversal is required. Some service providers provide NAT traversal, but
some do not. If you are unsure, check with your SIP provider.
• Send NAT Keep Alive: Check this box to allow the Cisco UC320W to
periodically send Keep Alive messages to the server to maintain the current
NAT mapping. Note: This option is available if you check the NAT Mapping
box.
Note: Other NAT settings are configured in the Systemwide SIP Parameters
section below.
Previous fields should be fill out as follows:
• Description: babyTEL
• Proxy: sip.babytel.ca
• Require registration: Check the box.
• Outbound Proxy: nat.babytel.ca:5065
Port is important
• Call Capacity: According to your babyTEL account
• Prefix dialed numbers with: 1 in the US (for instance)
• Company Name: Enter the business name.
• Account ID (often Account Phone Number): 11-digit number (main number in babyTEL account)
• SIP Domain Name: sip.babytel.ca
• Authentication ID: 11-digit number (main number in babyTEL account)
• Password: If your provider requires SIP authentication, enter the password
for your account. Typically this password is case sensitive.
• SRV Record Lookup: blank
• SRV Auto Prefix: Uncheck the box not to use this service.
• Local SIP Port: 5060
• NAT Mapping: Not required. If you are unsure, check with your SIP provider.
• Send NAT Keep Alive: Check this box to allow the Cisco UC320W to
periodically send Keep Alive messages to the server to maintain the current
NAT mapping. Note: This option is available if you check the NAT Mapping
box.
Systemwide SIP Parameters
This section of the page is available after you choose a provider. These settings
apply to all SIP providers.
• Codec: To start choose G711.
• Outbound FAX: Choose a fax transmission setting.
• NAT STUN Server: Do not configure.
• NAT Server IP Address (text box):
• Static IP Address for Site: Specify the public static IP address that is used
for Internet connections at your site. Note: This option is available if you
enabled NAT mapping for one or more SIP providers. This setting applies to
all SIP trunks.
• Static IP Address (text box): Enter the publicly routable static IP address
for your site.
I hop ethis helps,
BR,
Carlos
