SPANless Recording



• SPANless recording method uses Silent monitoring

and recording interface of CUCM

• SPANless is supported by CUCM 6.0 and higher

• SPANless requires 3rd generation phones

– 7906G, 7911G, 7921G with Aug 2008 maintenance update, 7925G, 7931G, 7941G, 7941G-GE, 7942G, 7945G, 7961G, 7961G-GE, 7962G, 7965G, 7970G, 7971G-GE, 7975G, and IP Communicator 7.0(1) (and later).

SPANless recording prerequisites



• Two recording modes are available with CUCM interface:• Automatic recording: Records all calls on line appearance.

Invoked by CUCM.• Selective recording: Allows user to record ad-hoc. Also allows

recording server to record based on business rules and events.

• ZOOM still provides its unique Pre-recording feature

SPANless – how doest it work



SPANless – how doest it work

• A customer calls in. • The call is routed to an Agent

who answers the call. • Cisco Unified Communications

Manager automatically sends two call setup messages to the Agent device.– 1st call is Agent stream– 2nd call is Customer

stream • Communications Manager

INVITES Recorder to both calls via SIP Trunk.

• Recorder accepts both calls and receives RTP streams from Agent device.

Cisco JTAPI

Voice Stream



• Free resources for network monitoring

• Some network architectures cannot be realized with

SPAN port

• Easier administration – no configuration of SPAN ports

necessary (OPEX)

– What if you want to move some department?

– Internal calls recording = RSPAN, VLAN split to meet SPAN capacity

• Higher reliability – system resources are better utilized

• Reduced CAPEX – need for fewer elements at the

branches

SPANless benefits



• 100% reliability of call recording, storage and playback

• Better control over branch locations

• Security: Both authenticated and encrypted mode can

never be recorded.

– Cisco plan support for CUCM 8.x

• Geo redundancy available with high bandwidth

utilization

• Built-in support of recording notification tones

Server #3



• Higher network traffic

• For PSTN recording only GW span works as simple trunk recording

• TAP switches are able to handle high traffic in large architectures with

centralized GW.

• 3rd generation phones only

• New devices 69xx, 89xx, 99xx. 69xx are not supported with

SPANless

• No active-active redundancy

• Interruption in recording if failure happens during the call

• If WAN capacity is limited, redundant recorder can be refused (network

intelligence)

SPANless disadvantages



• ZOOM CallREC ® supports all advantages of CUCM

recording interface:

• Geo-redundancy

• Load balancing

• Centralized architecture

• ZOOM CallREC® keeps own on-demand recording

method compatible with SPANless:

• Pre-recording and Post-recording feature enabled

• Authenticated mode supported

ZOOM solution



• ZOOM CallREC® supports combination of both

methods on one server:

• Customer does not have to replace all phones today

• GW trunk recording as a backup/redundant solution

• ZOOM CallREC ® identifies if devices are configured

for SPANless and expect the call on SPAN port

• If call forking is not coming (WAN limitation) CallREC

checks data on SPAN port
