The Enhanced XML CDR Importer is a piece of software that directly replaces the standard FusionPBX XML Importer. Each time a call is finished, the FreeSWITCH, through the mod_xml_cdr module, will call an HTTP PHP script that will import the call detail record into the database. It is called XML because FreeSWITCH actually uses an XML format to push the data.
I also have forgotten to make this public, but from some days ago the Signalwire Client C RPM for CentOS 7 and 8 is available. Signalwire Client C is the library that allows communication with Signalwire services. It is needed if you want to enable signalwire module.
I want to thanks the FusionPBX community for their sponsor. Without the given support this new capability wouldn't be possible. Today I have published into the FusionPBX some pull requests (for FusionPBX 4.4 and 4.5). This new capability gives your PBX the parent-child domain. This means an admin user will be able to manage more than one domain without being super-admins. The best-case scenario for this is new capability is the reseller one.
Once it is configured, you may give access to a reseller and let him manage their domains. I will explain how it works.
