Cisco Unified CallConnector Mobility Service
Technical Overview
Network Bandwidth
Requirement
If the routers are in different locations connected via private network,
the network should have sufficient capacity to support:
a. SCCP/Skinny traffic between the UCC Server and each of
the routers. The traffic to the UCC Server will be the number
of ephones controlled by the UCC Server multiplied by the
bandwidth required for one SCCP session.
b. Voice Media -- RTP (G.711 encoded) 128 Kbps for each call
handled by the Mobility Services. The network should have
the bandwidth and latency for the peak or maximum number
of calls that can handled by the Mobility Service.
c. Radius Messages -- UDP traffic from each router to the UCC
Server.
Note: The network should also allow the transport of UDP traffic
between the routers and the UCC Server.
Location of Routers
Generally the UCC Server should hosted with the largest CME router
in a multiple router configuration. The UCC Services are not sensitive
to the location of the routers, although it is assumed that the routers
are in one country.
Resources Required on
each router for the
Mobility Services
The Mobility Service requires the following to be configured on each
router:
a. Mobility-ephones and ephone-DNs. The Mobility Service
requires available mobility-ephone in the router of the SNR
user‘s ephone for processing the SNR calls. If the ephones
are not available, then the service is not launched.
b. Conferencing resources – since the mobility-ephones are
from each router and these ephones request the
conferencing services, the conferencing and DSP resources
have to be configured on each CNE router from which the
users will be using the Single Number Reach service.
c. CUE and Voicemail boxes – the user‘s calls are returned to
the user‘s voice mailbox. Each router is required to have
CUE installed, together with the Transfer-to-Voice Mailbox
script and a distinct pilot number to that router‘s transfer-to-
voice mailbox script.
d. Since the Mobility Service utilizes the resources of each
router, the CME features of shared DNs, Pickup, Transfer
and Conference need to be configured on each router for use
by the mobility service.
Dialing Plans and Dialing
Rules
The UCC Server allows administrators to setup the location,
extension number lengths, outside access codes for each router. The
