what is the communication when using the UC mobile client. When the call is made using officelink...... do you utilise the data network and break out from the office PBX. I was however led to believe that when you use officelink, the PBX makes a call to the number dialled via officelink. then makes a call back to the DN dialling the number from the UC client then "joins" them.
The reason i ask is im looking to see if UC client is worthwhile for worldwide travel out of the office.
