Determining the Software Version
To determine the version of Cisco IOS software running on a Cisco 3600 series router, log in to the router and enter the show version EXEC command:
router> show versionCisco Internetwork Operating System SoftwareIOS (tm) 3600 Software (c3600-is-mz), Version 12.2(2) XA5, RELEASE SOFTWAREUpgrading to a New Software Release
For general information about upgrading to a new software release, refer to Upgrading the Cisco IOS Software Release in Cisco Routers and Modems located at:
http://www.cisco.com/warp/public/130/upgrade_index.shtml
Feature Set Tables
The Cisco IOS software is packaged in feature sets consisting of software images—depending on the platform. Each feature set contains a specific set of Cisco IOS features.
Cisco IOS Release 12.2(2) XA supports the same feature sets as Cisco IOS Release 12.2(2) T, but Cisco IOS Release 12.2(2) XA can include new features supported by the Cisco AS3600 series.
Note If you have a Cisco.com login account, you can find image and release information regarding features prior to Cisco IOS Release 12.2(2) T by using the Feature Navigator tool at http://www.cisco.com/go/fn.
Caution Cisco IOS images with strong encryption (including, but not limited to, 168-bit Triple Data Encryption Standard [3DES] data encryption feature sets) are subject to United States government export controls and have limited distribution. Strong encryption images to be installed outside the United States are likely to require an export license. Customer orders may be denied or subject to delay because of United States government regulations. When applicable, purchaser and user must obtain local import and use authorizations for all encryption strengths. Please contact your sales representative or distributor for more information, or send an e-mail to export@cisco.com.
Table 3, Table 4, and Table 5 list the features and feature sets supported by the Cisco 3620 router in Cisco IOS Release 12.2(2) XA5. Table 6, Table 7, and Table 8 list the features and feature sets supported by the Cisco 3640 router in Cisco IOS Release 12.2(2) XA5. Table 9, Table 10, and Table 11 list the features and feature sets supported by the Cisco 3660 routers in Cisco IOS Release 12.2(2) XA5. These tables all use the following conventions:
•Yes—The feature is supported in the software image.
•No—The feature is not supported in the software image.
•In—The number in the "In" column indicates the Cisco IOS release in which the feature was introduced. For example, (2)XA2 means a feature was introduced in 12.2(2) XA2.

New Software Features in Cisco IOS Release 12.2(2) XA
The following new software features are supported by the Cisco 3600 series for Cisco IOS Release 12.2(2) XA:
Call Admission Control for H.323 VoIP Gateways
Before the call admission control feature, gateways did not have a mechanism to gracefully prevent calls from entering when certain resources were not available to process the call. This causes the new call to fail with unreported behavior, and could potentially cause the calls that are in progress to have quality related problems.
This feature set provides the ability to support resource-based call admission control processes. These resources include system resources such as CPU, memory, and call volume, and interface resources such as call volume.
If system resources are not available to admit the call, two kinds of actions are provided: system denial (which busyouts all of T1 or E1) or per call denial (which disconnects, hairpins, or plays a message or tone). If the interface-based resource is not available to admit the call, the call is dropped from the session protocol (such as H.323).
User Selected Threshold
This feature allows a user to configure call admission thresholds for local resources as well as memory and CPU resources. The list of local resources that are configured for call admission are described in the command description of "call threshold poll-interval."
With the call admission command, a user is allowed to configure two thresholds, high and low, for each resource. Call treatment is triggered when the current value of a resource goes beyond the configured high. The call treatment remains in effect until current resource value falls below the configured low. Having high and low thresholds prevents call admission flapping and provides hysteresis in call admission decision making.
With the call spike command, a user is allowed to configure the limit for incoming calls during a specified time period. A call spike is the term for when a large number of incoming calls arrive from the PSTN in a very short period of time (for example:100 incoming calls in 10 milliseconds).
Configurable Call Treatment
With the call treatment command, users are allowed to select how the call should be treated when local resources are not available to handle the call. For example, when the current resource value for any one of the configured triggers for call admission has reached beyond the configured threshold, the call treatment choices are as follows:
•TDM hairpinning — Hairpins the calls through the POTS dial peer.
•Reject — Disconnects the call.
•Play message or tone — Plays a configured message or tone to the user.
Resource Unavailable Signaling
This feature set supports the autobusyout feature where channels are busied out when local resources are not available to handle the call.
Autobusyout is supported on both channel associated signaling (CAS) and Primary Rate Interface (PRI) channels.
•CAS — Uses busyout to signal "local resources are unavailable."
•PRI — Uses either service messages or disconnect with correct cause-code to signal "resources are unavailable."
PSTN Fallback
The goal of PSTN fallback is to monitor congestion in the IP network and either redirect calls to the PSTN or reject calls based on the network congestion. Calls can be re-routed to an alternate IP destination or to the PSTN if the IP network is found unsuitable for voice traffic at that time. The user defines the congestion thresholds based on the configured network. This functionality enables the service provider to give a reasonable guarantee about the quality of the conversation to their VoIP users at the time of call admission.
Note PSTN fallback does not provide assurances that a VoIP call that proceeds over the IP network is protected from the effects of congestion. This is the function of the other Quality of Service (QoS) mechanisms such as IP Real-Time Transport Protocol (RTP) priority or low latency queuing (LLQ).
PSTN fallback includes the following features:
•Offers flexibility to define the congestion thresholds based on the network.
–Defines a threshold based on Calculated Planning Impairment Factor (ICPIF), which is derived as part of International Telecommunication Union (ITU) G.113.
–Defines a threshold based solely on packet delay and loss measurements.
•Uses Response Time Reporter (RTR) probes to provide packet delay, jitter, and loss information for the relevant IP addresses. Based on the packet loss, delay, and jitter encountered by these probes, an ICPIF or delay and loss values are calculated.
•Is supported by calls of any codec. Only G.729 and G.711 have accurately simulated probes. Calls of all other codecs are emulated by a G.711 probe.

H.323 Scalability and Interoperability Enhancements
The Cisco H.323 Scalability and Interoperability Enhancements feature upgrades the Cisco H.323 Gatekeeper (GK) and Cisco H.323 Gateway to comply with H.323 Version 3. The enhancements in this release include:
•Support for mandatory H.323 Version 3 elements in the gateway and GK, including:
–multipleCalls
–maintainConnection
–alternateTransportAddresses
–useSpecifiedTransport
•Support for H.225 call signalling over UDP.
•Address resolution using border elements (BE).
•Support for bandwidth request (BRQ) messages.
•Support for concurrent calls over a single H.225 call signalling channel.
For further details, please see http://www.cisco.com/univercd/cc/td/doc/product/software/ios122/122newft/122limit/122x/122xa/122xa_2/ft323sca.htm.
Inter-Domain Gatekeeper Security Enhancement (CSCds35228)
The Inter-Domain Gatekeeper Security Enhancement provides a means of authenticating and authorizing H.323 calls between the administrative domains of Internet Telephone Service Providers (ITSPs).
For further details, please see http://www.cisco.com/univercd/cc/td/doc/product/software/ios122/122newft/122limit/122x/122xa/122xa_2/ft_ctoke.htm.
Location Confirmation Enhancements for Alternate Endpoints
The Location Confirmation (LCF) Enhancements for Alternate Endpoints feature allows the Cisco IOS Gatekeeper (GK) to collect alternate routes to endpoints indicated by multiple LCF responses and convey the routes to the requesting (calling) endpoint. Currently, the GK sends LRQ messages to multiple remote zones. Endpoints in the zones return LCF responses to the GK. The LCF responses indicate an alternate route to that endpoint. The GK determines the best route to an endpoint based on which route has the lowest cost and the highest priority. The GK then forwards that route information to the requesting endpoint. However, the GK does not provide to the requesting endpoint all of the route information it received in LCF messages from the endpoints; it only provides the best routes.
The LCF Enhancements for Alternate Endpoints feature allows the GK to present more route information to the requesting endpoint, therefore providing alternate routes to endpoints that can be used if the best route is busy or does not provide any alternate routes. The LCF Enhancements for Alternate Endpoints feature can be used on GKs that originate LRQs as well as directory GKs that forward LRQ messages.
The LCF Enhancements for Alternate Endpoints feature provides a new timer that you can configure to choose the number of alternate routes you want the GK to collect. Upon the timer expiration, the resolved address and alternate endpoints from all the LCFs received by the GK will be consolidated in a single list and sent as alternate endpoints in the ACF or LCF messages from the GK. If this feature is not enabled, the GK stops collecting routes if the best response is received before the LRQ timer window expires. After you enable the feature, the GK only stops collecting routes after the best response is received and the configured number of alternate routes have been gathered.
