A parameter can be associated with each ingress and egress route in your dial plan. Parameters represent a single attribute line in the VRC-generated dial-peer definition.
Certain route attributes (destination-pattern, session target, voice-port) are restricted and are generated based on the list of attributes for the route. Other route attributes can be added to the route as parameters because they do not affect the dial plan.
This topic describes the route parameters that you can add to an ingress or egress route, and these parameters do not affect the dial plan.
Parameters include:
Route Parameter |
Description |
direct inward dial (DID) |
Enable the DID call treatment for the incoming called numbers. When this feature is enabled, the incoming call is treated as if the digits were received from the DID trunk. The called number is used to select the outgoing dial peer. No dial tone is presented to the caller. |
icpif |
Impairment/Calculated Planning Impairment Factor (ICPIF) - Specify the maximum acceptable impairment factor for the voice calls sent by the selected dial peer. |
inbound application |
Creates an application and indicates the location of the corresponding Tool Command Language (TCL) files that implement this application. |
inbound clid network-number |
Configures a network number in the router for calling line ID (CLID) and to use it as the calling party number. |
inbound clid restrict |
Prevents the calling party number from being presented by calling line ID (CLID). |
inbound clid strip |
Prevents the second network number from being sent in the CLID information. |
inbound info-digits |
Prepends info digits to the calling number. |
inbound max-conn |
Sets maximum connections per peer; "no" sets to unlimited. |
inbound voice-class aaa |
Allows you to use the authentication, authorization, and accounting TCL verbs on this route. |
information type |
|
ip precedence |
Configure the value set in the IP precedence field when voice data packets are sent over the IP network. This parameter should be used if the IP link utilization is high and the quality of service for voice packets needs to have a higher priority than other IP packets. The ip precedence parameter should also be used if RSVP is not enabled and the user would like to give voice packets a higher priority than other IP data traffic. |
ip udp checksum |
Enable UDP checksum calculation for each of the outbound voice packets. If you suspect that the connection has a high error rate, you should enable the ip udp checksum parameter to prevent corrupted voice packets forwarded to the digital signal processor (DSP). |
outbound acc-qos |
Define the acceptable quality of service (QoS) for any outbound call on a Voice over IP (VoIP) dial peer. |
outbound application |
Creates an application and indicates the location of the corresponding Tool Command Language (TCL) files that implement this application. |
outbound codec |
Specifies the voice coder rate of speech for calls to this peer. |
outbound dtmf-relay |
Transports DTMF digits across IP link. |
outbound expect-factor |
Specifies when the router generates an alarm to the network manager, indicating that the expected quality of voice has dropped. |
outbound fax nsf |
|
outbound fax protocol |
Specifies the fax protocol for the dial peers. Choose from cisco, none, system, t38, ls_redundancy, hs_redundancy value]} |
outbound fax rate |
Selects the fax transmission speed to be attempted when using this dial peer. |
outbound max-conn |
Sets maximum connections per peer; "no" sets to unlimited. |
outbound modem passthrough nse codec |
Modem passthrough provides the transport of modem signals through a packet network by using pulse code modulation (PCM) encoded packets. Named signaling event (NSE) codec- voice compression for speech or audio signals. |
outbound modem passthrough nse payload-type |
NSE payload type - Payload types can differ between local and remote endpoints. Use this parameter to transmit one payload type value and receive a different payload type value. |
outbound modem passthrough system |
Specifies that you want to use the voice service VoIP configuration default to simplify gateway configuration. |
outbound playout-delay maximum |
Playout-delay parameter tunes the playout buffer on digital signal processors (DSPs) to accommodate packet jitter caused by switches in the WAN. Maximum is the upper limit of the jitter buffer, or the highest value to which the adaptive delay is set, in milliseconds. |
outbound playout-delay minimum |
Lower limit of the jitter buffer,or the lowest value to which adaptive delay is set. Choose from default (40 ms), low (10 ms), or high (80 ms). |
outbound playout-delay mode |
Selects fixed or adaptive mode for the jitter buffer on DSPs. |
outbound playout-delay nominal |
Amount of playout delay in milliseconds applied at the beginning of a call by the jitter buffer in the gateway. The range is 0 to 1500. |
outbound settle-call |
To force a call to be authorized with a settlement server. |
outbound voice-class aaa |
Allows you to use the authentication, authorization, and accounting TCL verbs on this route. |
resource guarantee |
|
roaming |
Enable roaming capability of a settlement provider if that provider can authenticate a roaming user and route roaming calls. A roaming call is successful only if both the settlement provider and the outbound dial peer for that call are roaming-enabled. |
session target |
Specify a network-specific address or domain name for a dial peer. Whether you select a network-specific address or a domain name depends on the session protocol you select. |
snmp |
Simple Network Management Protocol (SNMP) manager that uses SNMP messages when voice quality drops. |
supplementary-service pass-through |
Configures the supplementary service feature to transparently pass supplementary service to the next gateway. |
vad |
Enable voice activity detection (VAD) for the calls on this route. |
