I am having a hard time writing a query for a GetXMLDocumentData step. I was trying to model it off one in a previous script, but I am striking out. Here is the XML that was returned to me from a REST call. TEXT[<?xml version=\"1.0\" encoding=\"UTF-8...

This may be a bit dated, but I never had good luck with SCCP and analog gateways for fax machines. I have had good luck with MGCP/CUCM on analog gateways.Here is one of my templates I have used for a long time. no ccm-manager fax protocol cisco ...

I am just guessing here because I have always had both the publisher and subscriber when a cluster was built initially. You may need to create the [JTAPI]_2 application user with the same password and group assignments as the [JTAPI]_1 account. The i...
