VoIP ALG

An application-layer gateway provides basic proxy features. Serving as an

ALG proxy, the system maps many network appliances into one or more

public IP addresses and provides the connectivity and management for IP

phones. The ALG must first recognize and register a network appliance before

it presents the IP telephone or data device through its public WAN port. The

system contains an MGCP, SIP and H.323 call-control proxy ALG. VoIP phones

and client adapters have to be configured to point to the system, which

serves as a call-control server, proxy, gatekeeper or gateway. For corporate

customers with high-end routers and firewalls, the system can be configured

as a VoIP Application Layer Gateway only. This allows all of the normal data

traffic to continue to be handled by the existing network devices, and

voice/video traffic to be handled by the system. For this configuration, the

system WAN Ethernet port is connected to the internet. The system LAN

Ethernet port is connected to a port on the desired LAN Ethernet switch. The

system can reside on one subnet and be accessed by VoIP devices on other

subnets through the router.

⇒

Select VoIP ALG.

o TFTP server IP address --



 This allows the system to act as a TFTP

server providing subsequent configuration information to other VoIP

phones or devices.

o Use ALG Alias IP Address --



 Enter the IP address on the LAN that

endpoints communicate with. Generally, this is the same as the LAN IP

address. In some cases, the ALG addresses will not correspond to the

addresses of the LAN or the WAN ports (e.g. when VRRP is enabled).

The addresses will be alias addresses that have been configured on the

ports. In general, the user should leave this feature disabled. Check

this box to enable the below IP parameters to be changed.



Note; VRRP is only supported in the 5300 and 6400

platforms.

.”

o Do strict RTP source check --



 This feature is designed to

prevent a specific RTP-based Denial-of-Service attack as well as

address network based gateways that periodically fail to stop

sending an RTP stream when a call ends. If the source of an

inbound RTP stream does not match the IP Address and Port for

an existing outbound RTP stream, then it is assumed that the

inbound stream is "rogue RTP". When rogue RTP is detected, a

syslog message is generated and the inbound stream is

dropped.

o Registration --



 The SIP registration settings allow the device to

manipulate the endpoints registration rate.

o SIP Expires Override (s) --



 SIP Expires override field specifies

the number of seconds a registration should be valid. The system uses

this value to re-write the expires value returned from the soft-switch.

The value is entered in seconds i.e. 30 will be 30 seconds.

o Soft-Switch Expires Override (s) --



 SIP Soft-Switch expires

override field specifies the number of seconds that should be used

when forwarding registration messages to the soft-switch. This should

be higher than the rate pacing value, otherwise, the soft-switch may

consider the phones registration to have expired. If this field is not set,

the phones value is forwarded unchanged.

o Register Rate Pacing (s) --



 If the SIP Expires override field is set

to a lower value, the number of registration messages may overload

the soft-switch. In order to prevent this, you can set the Register

Rate pacing field to the number of seconds to wait before forwarding

a register message from one phone to the soft-switch. Any register

messages received before this time will be locally answered by the

system. For example, you may set the expires value to 60 and the

pacing value to 1800 to have the phone register to the system every

minute, but only let a register message through to the soft-switch

every 30 minutes.

o LAN/Subscriber Side Gateway --



 The LAN/Subscriber side

gateway allows PSTN calls to go out to a local gateway. This gateway

can also be used in survivability mode. The LAN/Subscriber Side

Gateway is used to configure a LAN/Subscriber side SIP gateway to

which calls that are not for a registered phone can be sent. The name

of the gateway is a locally meaningful name. These two fields must

both be filled in, or both be empty.

MGCP Re-registration Rate needs to be changed, enter a value

between 1 and 5. Generally, this value does not need to be modified.

The default value is 5 messages per second.

o MGCP Re-Registration Retry Delay (s) --



 The system re-registers

clients when it starts up. If any of these re-registration requests fail,

the system will wait for the configured number of seconds and then

retry the re-registration for the clients that failed. The system will

make at most 10 re-registration requests for failed attempts. If the

MGCP Re-registration Retry Delay needs to be changed, enter a

value between 30 and 60 seconds. Generally, this value does not need

Send Request-In-Progress checkbox enables the sending of

Request-In-Progress messages when lengthy operations are done,

such as doing a DNS lookup for a domain-name.

o Domain-Name --



 The system can strip the given domain-name

from incoming calls when attempting to match the alias to a client and

strip all domain names from outgoing calls. When the local domain-

name is specified, the system will strip this domain name from any

destination aliases in incoming calls if present. This will allow

endpoints to register with just their extension instead of the whole

user@domain alias. Domain-name settings can be used to strip

domain-names from aliases. This can be used to allow endpoints to

dial destinations composed of a user or alias part, the "@" sign, and a

host or IP part, e.g. "user@company.com", "123@company.com", or

"[email protected].3.4". When this call is sent out, or received from the

outside, the host or IP part can be stripped to allow normal alias

matching.

o Local-Domain --



 Local domain specifies the local domain of the

system. This domain (if specified) will be stripped from any incoming

calls before matching the alias.

o Strip Outgoing Domains --



 Strip outgoing domains will cause

the domain part to be stripped from any outgoing calls.

o Convert Digits to E.164 --



 Convert digits to E.164 will convert

the called alias to an E.164 alias if the user part is digits only. For

example, if "123@company.com" is called, "@company.com" will be

stripped and the resulting alias is "123". Since this alias only contains

digits, it will be converted to an E.164 alias.

o Terminal Type --



 Terminal Type specifies what client type shall be

signaled to the gatekeeper. The Terminal Type is used to specify the

type of terminal that the system should use. It can be either endpoint

or gateway.

o Multicast Messages --



 Some RAS messages can be multicast in

order to automatically detect gatekeepers. Multicast Messages

determines whether the system should listen and process multicast

RAS messages such as Gatekeeper Requests (GRQ) and Location

Requests (LRQ). Processing these messages allow endpoints to

automatically detect the system but if multiple systems process

multicast messages, it can cause a conflict.

o Bandwidth Settings --



 Bandwidth Settings specifies the

bandwidth to allow for H.323 calls. The bandwidth is specified in kbps

and if it is set to 0, bandwidth management is not enforced. Only calls

with media traversing the system is counted towards the bandwidth

maximum. This number apples to the TOTAL bandwidth maximum

(payload + overhead); the actual payload amount allowed through will
