We have noticed that unless the phone fields are formatted to USA i.e. (XXX) XXX-XXXX then Salesforce.com doesn't pop an inbound call. Has anyone outside of the US had the same experience and found a fix?

Dear Jed, as your reseller we have logged a call for this issue and will work through our support desk and through I3's support centre. A support call has been created at 22:11pm last night, your reference is: ELC-04560-G8R5G0 Many thanks, Karl.

We currently have a thread open with development regarding this scenario. I'll post back here once a consensus has been reached.

Our dev team opened a case with Salesforce, as this is something they will need to address on their end (we confirmed that the same behavior exists while using the Salesforce demo adapter).

Thanks Malcolm. I have also raised a ticket but obviously you are further down the reply chain than I am.
