Breaking Changes

This section explains the changes that you must consider when migrating to pascom 19

  • Snom Pickups where changed to EXTENSION|*8 syntax. See Snom Desktop Phones.
  • Trunk Failover deleted without alternative tools. No migration and no direct workaround. Support can help with an outbound script, if needed.
  • IAX trunks deleted without alternatives.
  • Swap is now disabled by default. This can break virtualised setups with memory lower then 1 GB, please configure more memory in this case.
  • Call groups are automatically converted to teams. The callgroup feature has been removed and customers should configure teams instead.
  • Port forwarding for UDP 3478 is now mandatory, otherwise video tools will not work.
  • A new provisioning is required for beronet Gateways.
  • pascom SOHO Server is no longer compatible. Please perform a hardware upgrade to the pascom Appliance or use the
  • Automatic Trunk Updates will be performed for Telekom, peoplefone (DE, AT, CH), HFO, Sipgate Trunking, RKom, t-m-net, sipcallch, seabix, mnet, easybell and qsc/plusnet. Please check your trunk after update.
  • Cronjob Scripts (before/after) are no longer supported
  • Tunks which have their own template, get this automatically assigned again. All customizations using a generic template are removed

Known Issues

These problems are known to us and we are already working on a solution

  • Onsite Telekom trunks only work if an outbound proxy is used. To do this, select the appropriate interface in the trunk instead of “default / NAT”.
