We recently set up an Expressway pair for a customer to route their video calls to their webex site. with this, we also configured a simplified dialing string allowing them to dial 8 + <meeting number> and then created a transformation on the Expressway-C that appends @customer.webex.com as specified in the Cloud deployment guide.
What the guide fails to mention is that due to how calls are processed through the Expressway that to use a transformation in this manor requires that an RMS license is used instead of the free Cloud traversal license for Webex calls with Expressway X8.7.
The only thing I can think of is using a Normalization script in CUCM for the trunk so the @customer.webex.com is already there when the call is sent to the Expressway. The problem I have is i have no experience with these scripts. Can anyone shed some light on how to make this transformation happen with a script or if its even possible?
Thanks,
