AAR 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.

List of items to configure on all routers/switches

1. Disable ip domain lookup using command “no ip domain-lookup”

2. Disable exec timeout using command “exec-timeout 0 0” under line vty mode.

Service parameters to change on startup

1. BRQ – True

2. AAR – True

3. Call Diagnostics enabled – True

Media Template

1. Create a MRG for each resource at each site. HQ conf, HQ MOH, HQ Xcode, same for BR1. Do not add any unused resources to any group. The devices with MRGL assigned can access only the resources in the groups and does not have access to any unused resources. Total 6 MRG’s required.

2. Create a MRGL for each type of device, one for phones one for gateways. Total 2 MRGL’s

3. if one site requires Mulitcast and another requires unicast. Then uncheck “Allow multicast” under the appropriate MRG. The audio source should be multicast enabled.

4. It seems gateways cannot access MRGL from the Device pool. So you have to apply MRGL at the gateway level. All other devices (phones etc) are able to access MRGL from the Device pool if you have not set a MRGL under the device.

H323 template

1. voice class codec, g711 as first preference and g729 second

2. voice class h323 with timeout 3

3. dial-peer to match incoming call leg

4. two dial-peers to send calls to CCM. enable no vad on these dial-peers and also dtmf-relay
5. 4 outgoing dial-peers for 911, local, long and international

6. enable qos for signaling

voice class codec 1
codec preference 1 g711alaw (under most circumstances g711ulaw is enough, unless the site is in Europse or a country that uses alaw)
