Understanding VOS3000 Gateway Types

VOS3000 uses two fundamental gateway types that serve different purposes in the call flow architecture. Understanding the distinction between these gateway types is essential for proper system configuration and troubleshooting. VOS3000 Gateway Configuration

Routing Gateway Configuration (VOS3000 Gateway Configuration)

Routing gateways are configured to send calls to termination providers and vendors. Each routing gateway represents a destination for outbound calls and contains all parameters needed for proper call routing and billing.

Gateway Type Configuration Details (VOS3000 Gateway Configuration)

VOS3000 supports three gateway types, each with specific use cases:

Static Gateway

Configuration for Static Gateway:
– IP Address: Required – Enter vendor’s IP address
– Port: SIP default 5060, H.323 default 1720
– Authentication: IP-based (no username/password needed)
– Best for: Dedicated vendor connections, known IP addresses

Steps to configure:
1. Navigation → Operation Management → Gateway Operation → Routing Gateway
2. Click “Add” to create new gateway
3. Select Gateway Type: Static
4. Enter Gateway Name (unique identifier)
5. Enter IP Address of vendor gateway
6. Set Protocol (SIP or H.323)
7. Set Signaling Port
8. Configure Line Limit
9. Click “Apply” to save

Dynamic Gateway

Configuration for Dynamic Gateway:
– IP Address: Not required – discovered through registration
– Registration: Vendor registers to VOS3000
– Authentication: Username/password required
– Best for: Vendors with dynamic IPs, NAT traversal

Steps to configure:
1. Create gateway with type “Dynamic”
2. Vendor must configure their end to register to VOS3000
3. VOS3000 learns IP from registration
4. Set registration expiry parameters
5. Monitor registration status in “Online Routing Gateway”

Registration Gateway

Configuration for Registration Gateway (Outbound Registration):
– VOS3000 registers TO the vendor
– Required when vendor requires authentication
– Configuration via “Registration Management”

Steps to configure:
1. Navigation → Operation Management → Registration Management
2. Add new registration entry:
– Mark: Unique identifier
– User Name: Vendor-provided username
– Authentication Password: Vendor-provided password
– Server IP: Vendor’s registration server
– Signaling Port: Typically 5060
– Register Period: Registration interval (default 3600s)
3. In Routing Gateway, select type “Registration”
4. Reference the Mark from Registration Management
5. Monitor registration in Registration Management view

Mapping Gateway Configuration (VOS3000 Gateway Configuration)

Mapping gateways handle incoming calls from customers and are associated with customer accounts. Each mapping gateway configuration determines how VOS3000 identifies and bills the originating party.

Gateway Authentication Methods

VOS3000 supports multiple authentication methods for gateways. Selecting the appropriate method depends on your security requirements and network topology.

Codec Configuration (VOS3000 Gateway Configuration)

Codec configuration determines voice quality and bandwidth usage for calls through each gateway. VOS3000 allows codec preferences to be set per gateway. (VOS3000 Gateway Configuration)

Supported Codecs

CodecBitrateQualityBandwidth (with overhead)G.711 (alaw/ulaw)64 kbpsExcellent~87 kbpsG.7298 kbpsGood~31 kbpsG.723.15.3/6.3 kbpsFair~21 kbpsGSM13 kbpsFair~36 kbps

Configuring Codec Priority

In Gateway Additional Settings → Codec:

1. Add supported codecs in priority order
2. Most preferred codec at top of list
3. System parameter default: SS_VALUE_ADDED_CODECS

Example Configuration (Low Bandwidth Priority):
┌─────────────────────────────────────┐
│ Priority │ Codec │ Type │
├─────────────────────────────────────┤
│ 1 │ G.729 │ Audio │
│ 2 │ G.723.1 │ Audio │
│ 3 │ G.711a │ Audio │
│ 4 │ G.711u │ Audio │
└─────────────────────────────────────┘

Example Configuration (Quality Priority):

│ 1 │ G.711u │ Audio │
│ 2 │ G.711a │ Audio │
│ 3 │ G.729 │ Audio │
└─────────────────────────────────────┘

DTMF Configuration

DTMF (Dual-Tone Multi-Frequency) handling is critical for IVR systems and calling card platforms. VOS3000 supports multiple DTMF modes.

DTMF Mode Options

DTMF ModeProtocolReliabilityBest ForRFC 2833SIPHighMost SIP devices, recommendedInbandSIP/H.323LowLegacy devices onlySIP INFOSIPMediumSpecific vendor requirementsH.245 AlphanumericH.323HighH.323 gateways (default)

Gateway Groups (VOS3000 Gateway Configuration)

Gateway groups allow you to organize multiple gateways for routing purposes. This is useful for load balancing, redundancy, and access control.

Gateway Group Configuration

Location: Navigation → Operation Management → Gateway Operation → Gateway Group

Parameters:
– Gateway Group Name: Descriptive name for the group
– Line Limit: Total capacity for the group
• None: Use individual gateway limits
• Set value: Override individual limits
– Number of Routing Gateways: Count of routing GW in group
– Number of Mapping Gateways: Count of mapping GW in group

Use Cases:
1. Route balancing across multiple vendors
2. Restrict specific customers to specific vendors
3. Implement failover groups
4. Organize gateways by destination or quality tier

Monitoring Gateway Status

VOS3000 provides real-time monitoring of gateway status through the Online Gateway views.

Frequently Asked Questions

What is the difference between Static and Dynamic gateway types?

Static gateways use a fixed IP address that you configure manually – VOS3000 always sends calls to that IP. Dynamic gateways learn the IP address from SIP registration – the gateway device registers to VOS3000, and VOS3000 uses the registered IP for routing. Use Static when the vendor has a fixed IP, and Dynamic when the device may have a changing IP or is behind NAT.

How do I configure a gateway for a vendor that requires outbound registration?

First, create an entry in Registration Management with the vendor’s server IP, username, and password. Then create a Routing Gateway with type “Registration” and reference the Mark field from Registration Management. VOS3000 will register to the vendor and use that registration for routing calls.

What should the Line Limit be set to?

Line Limit should match your agreement with the vendor or the actual capacity of the gateway. Setting it too high may result in call failures when the vendor cannot handle the load. Setting it too low wastes available capacity. Monitor ASR and ACD to determine optimal settings.

How do I implement gateway failover?

Configure multiple routing gateways with the same prefix but different priorities. Lower priority values are tried first. If a call fails, VOS3000 will try the next gateway in priority order. You can also use Gateway Groups to organize failover paths.

Why is my gateway showing as offline in VOS3000?

For dynamic gateways, check if registration is working properly by examining Registration Management. For static gateways, verify the IP is reachable (ping test), firewall rules allow the SIP port, and the gateway device is powered on and operational. Check system logs for registration or connection errors.
