After installing the CoMo for Nokia client, the first thing you need to do
to successfully sign-in is to get the configuration settings fields correct in
the settings dialog. We've received a number of questions on what value should
be used for the “Server URL” configuration field. Many people do not know what
to enter for this field or make the mistake of using the FQDN (fully qualified
domain name) or IP address of Microsoft Office Communications Server 2007 R2
(OCS) Access Edge Server. For example, https://sipalt.access.contoso.com:443
where 443 is the port used for remote user access.
Before we hand you the answer, let us briefly walk you through the topology
that will be used for the CoMo for Nokia client to connect to the OCS
environment. CoMo for Nokia is not a direct Session Initiation Protocol (SIP)
endpoint like other supported OCS end points such as Microsoft Office
Communicator, Microsoft Office Communicator Phone Edition and Microsoft Office
Communicator for Windows Mobile. CoMo for Nokia uses the Communicator Web
Access (CWA) server component which plays the role of Mobile Communicator
Express (MCX) to connect the CoMo for Nokia client to the OCS environment and
acts as a gateway to the various OCS functions.
The CWA/MCX gateway between CoMo for Nokia translates HTTP requests to OCS
actions (and vice-versa) and also has an implementation for mobile
optimization. So in order for the CoMo for Nokia unified communications client
to have access to your OCS enterprise deployment, CWA is a pre-requisite. For
more information on planning for Communicator Mobile access refer to

By now you must have figured out the answer but let me go ahead and spell
it out, so for the “Server URL” configuration field in CoMo for Nokia client
user should fill the OCS’s CWA server URL address, for example
https://cwa.contoso.com, this is provided by your enterprise system
administrator. This server URL address is same as the one that you might use in
web browser to access the OCS presence, IM, and conferencing features of OCS
from web browser without installing a client or connecting through a VPN.
