Significance of $ in dial-peer destination pattern

Posted: October 25, 2006 by cciestudy in Gateways

$ means “end of digits” and is used for a more specific match. If you have two dial-peers with the same pattern and one with $ and the other without $, then call routing logic will always match the one with $, because that is more specific. Even if you give a lower preference to the dial-peer with $, still it will be matched because by default the dial-plan hunting algorithm is more specific match first and then preference.

dial-peer voice 10 pots

destination-pattern 1000

port 1/0/0

dial-peer voice 11 pots

destination-pattern 1000$

port 1/0/0

preference 5

In this case, always dial-peer 11 will be used to route calls to 1000, even though it has a lower preference.

Gatekeeper – Viazone behaviour

Posted: September 11, 2006 by cciestudy in Cisco General, Gatekeeper

How to trigger via zone behaviour?

Local zones – always enable outvia on the destination zone

Remote zones – use invia or outvia on the remote zone

Via-zone gatekeepers differ from legacy gatekeepers in how LRQ and ARQ messages are used for call routing. Using via-zone gatekeepers will maintain normal clusters and functionality. Legacy gatekeepers examine incoming LRQs based on the called number, and more specifically the dialedDigits field in the destinationInfo portion of the LRQ. Via-zone gatekeepers look at the origination point of the LRQ before looking at the called number. If an LRQ comes from a gatekeeper listed in the via-zone gatekeeper’s remote zone configurations, the gatekeeper checks to see that the zone remote configuration contains an invia or outvia keyword. If the configuration contains these keywords, the gatekeeper uses the new via-zone behavior; if not, it uses legacy behavior.

For ARQ messages, the gatekeeper determines if an outvia keyword is configured on the destination zone. If the outvia keyword is configured, and the zone named with the outvia keyword is local to the gatekeeper, the call is directed to a Cisco Multiservice IP-to-IP Gateway in that zone by returning an ACF pointing to the Cisco Multiservice IP-to-IP Gateway. If the zone named with the outvia keyword is remote, the gatekeeper sends a location request to the outvia gatekeeper rather than the remote zone gatekeeper. The invia keyword is not used in processing the ARQ.

PPP Virtual template and Frame-relay

Posted: August 30, 2006 by sankar in QOS, WAN

To configure a virtual template for MLP LFI on a frame-relay subinterface, you have to remove the DLCI configured under that subinterface first before reapplying it back with the ppp keyword.

int s0/0

no frame-relay interface-dlci 30

frame-relay interface-dlci 30 ppp virtual-template 1

Apply any LLQ, IP settings, ppp configs under the virtual template interface.

Alias huntgroups in SRST

Posted: August 27, 2006 by sankar in SRST, System

Have phones 2001,2002,2003 in SRST mode in a router. Calls coming into the system from PSTn should hit 2001 first and then on 2003.

alias 1 6175222001 to 2001 preference 1 cfw 2003 timeou 4 huntstop
alias 2 6175222002 to 2001 preference 1 cfw 2003 timeout 4 huntstop
alias 3 6175222003 to 2001 preference 1 cfw 2003 timeout 4 huntstop

Dialplan pattern doesnt have any effect in the called number when alias is configured. So you have to configure full 10 digits in the alias command. Alias

Call Park

Posted: August 23, 2006 by cciestudy in Callmanager Features

When you park a call, Callmanager will search the available Park numbers configured on the server that is processing the calls and will also look up the partitions that are available in the CSS of the phone and will pick the first available part number that is defined in a partition that is reachable by the phone.

When you go to another phone to retrieve the parked call, Callmanager will search for the parked call by using the CSS of the device.

This can create an issue if you create same park numbers in different partitions in different servers. It is recommended to give different park number ranges for different servers.

Make sure the call pickup group numbers does not overlap with the exiting dial plan

Call Pickup features include Pickup, GPickup, and OPickup:

•Pickup allows you to answer a call that is ringing on another phone within your “group” (a collection of extensions that your system administrator defines).

•GPickup allows you to answer a call ringing on a phone in another group.

•OPickup allows you to answer a call ringing on a phone in another group that is associated with your group

Configuring PPP multilink and fragmentation over Frame-relay

* Remove ip address of serial subinterface interface

* Remove DLCI of subinterface.

* Its recommended to do this configuration on the remote site first.

AAR template

Posted: August 15, 2006 by cciestudy in Template

1. Check the dial plan to find out if the calls between the sites are long distance or international.

2. If the calls are long distance, then you need to create only 1 AAR group with the prefix of 91. If the calls are international, then you would need to create a AAR group for each site.

3. Check the dial plan to see if the calls to the other site are using the local gateway only. If yes, then you can reuse the route pattern. Also you can reuse one of the existing CSS that has access to that route pattern as the AAR CSS. If no, then create a route pattern to specifically match the AAR calls and add it to the long distance or international partition for that site.

IPIPGW Gatekeeper lookup

Posted: August 13, 2006 by cciestudy in Gatekeeper

When using IPIPGW, you need to define a zone prefix to route calls. invia zones does not use the default technology.

CCM Server name

Posted: August 12, 2006 by cciestudy in System

The CCM server name that you give under System > Server should correspond to the actual name of the server used during install. You cannot change this later.

MoH Scenarios

Posted: August 12, 2006 by cciestudy in Media Resources

A. Unicast G711 everywhere

1. Create region for MoH. G711 with all other regions.

2. Do not enable multicast in audio source, server, MRG

3. Enable only G711 in service parameter (Default)

B. G711 multicast everywhere

1. Create region for MoH. G711 with all other regions.

2. Enable multicast in audio source, server, MRG. Set hop count to 5.

3. Enable only G711 in service parameter (Default)
4. Enable multicast in infrastructure (igmp snooping in switches, pim sparse-dense in routers)

C. G711 multicast everywhere, remote site uses MoH from local SRST flash

1. Create region for MoH. G711 with all other regions.

2. Enable multicast in audio source, server, MRG. Set hop count to 1.

3. Enable only G711 in service parameter (Default)
4. Enable multicast in HQ and Remote LAN infrastructure (igmp snooping in switches, pim sparse-dense in routers), Disable multicast in WAN infrastructure.

5. Enable SRST MOH feature from flash.

6. Enable loopback interface in SRST router for PSTN users to hear MoH.

D. G711 multicast at HQ, G711 unicast at Remote

1. Create region for MoH. G711 with all other regions.

2. Enable multicast in audio source, server, MRG. Set hop count to 1.

5. Create two MRG, one with multicast enabled for HQ and one with no mulitcast for BR1.

E. G711 unicast at HQ site, G729 unicast at remote

1. Enable Service parameter for G711 and G729

2. Use the HQ device pool for MOH server (assuming HQ device pool uses g729 for remote)

3. Do not enable multicast

F. G711 multicast at HQ, g729 multicast at remote

1. Enable Service parameter for G711 and G729

2. Use the HQ device pool for MOH server (assuming HQ device pool uses g729 for remote)

3. Enable multicast in audio source, server, MRG

4. Enable multicast in infrastructure

G. g729 unicast at remote using transcode

1. Enable only G711 in service parameter

2. Put MoH server in HQ device pool (assuming HQ uses G729 for remote)

3. Add a transcoder to MRGL of MoH server

I. HQ uses G711 multicast, remote uses G729 unicast, all PSTN uses hear tone on hold

1. Use HQ device pool for MoH server

2. Enable multicast on Audio source and server.

3. Create 2 MRG, one with multicast, one without multicast

4. Enable g711 and g729 in the service parameter

5. Create a third MRG and MRGL with no MOH and apply that directly to gateways

MoH server using Trancoder

Posted: August 12, 2006 by cciestudy in Media Resources

If the remote device does not support the codec of the MOH stream, then MOH server can trigger a transcoder. You would need to configure a MRGL with transcoder resource in the MoH servers device pool. In this case, CCM does not use the trancoder of the remote device. It will only use the transcoder of MOH server.
