  • Hotfixes can be easily removed if necessary
  • Smaller download size

To install the hotfix execute setup.msp and follow the Installation Wizard.

Hotfix 5 addresses following issues:

  • Fax transmission gets distorted on emulated ISDN connection.
  • Not all SwyxPhones were moved to fallback PhoneManager in case of outage of master PhoneManager.
  • User with extension '0' (Operator) is not reachable anymore if 'Use for external outgoing calls' is disabled on SwyxGate line
  • SwyxServer may cause a memory heap corruption under certain conditions, when delivering a call to a SwyxIt! and to a SIP device in parallel

Added new functionality with Hotfix 2:

  • Support for SIP links with no registration

To create a registration less SIP link you have to configure the 'registrar' configuration entry as magic string "noregistration". This configuration is either possible with the registrar field on the SIP property page on the link, or with the registrar attibute in the SIPProviderProfile element in the SIPProviderProfiles.config - XML file.

Further information on this can be found in the knowledgebase article

For the successful operation the SIP INVITE messages coming from the SIP provider should fullfil one of the following conditions:

  • all messages come from the IP address of the configured proxy
  • the URI in the To header has to include the host part (after the @) of the provider's realm.

Hotfix 2 addressed the following issues:

  • No caller list entry if incoming call is redirected by GSE script.

  • Holding a call routed through T-Online SIP Link does not work correctly.
