Applies To

This information applies to:

  • All PBX devices
  • All DECT devices
  • Linux Application Platform

Configuration Changes

Changed Semantics of conditional Call Forward

From the beginning, phone numbers used as a condition in an E.164 setup needed to be configured as full numbers starting from the root node. This is obviously wrong so that it has been fixed for v13r1 (see fix 13402 - PBX use adjusted number for checking numbers on call forward).

Known Problems

Main Memory (RAM) Considerations

New firmware always has more features which in turn requires more resources. Growing firmware will thus consume both more flash and RAM for sure. A given system configuration will run flawlessly after a firmware largely only if there is still enough memory left after boot. As a rough rule of thumb, a v13r1 release will consume x.xMB RAM and x.xMB flash more compared to a v12r2 firmware.

Standard configurations which are according to spec will run on all supported hardware. However, unusual configurations may not. It is a good idea to examine both flash and RAM memory left on high load situations in your existing configuration to see if there is enough resources left for an upgrade. Please find details in Reference:Device Health Check.

Special care has to be taken for old devices with less memory than suggested by current specs. Most notably, these are the older IP30x models (hardware build 306 or less, which had 16MB RAM as opposed to 32MB in the current models). We do not recommend to upgrade such old hardware to a current firmware version unless it has been determined that the configuration in question will work.

Flash Memory Considerations

New firmware comes with new code for new features which consumes more flash memory for the firmware image. For this reason, the IP800/IP22/IP24/IP38/IP302/IP305/P??? may run out of flash memory during upgrade to v13r1. Here is the recommended procedure for upgrade on such devices:

  • save entire configuration
  • reset to factory defaults
  • load saved configuration (this will reorganize flash memory usage)
  • upgrade to new firmware

When there is still not enough flash memory available to store the new firmware, the web GUI will issue a Firmwareupdate failed:no space during firmware upload. If the firmware upload is done using the update client, a Error 0x00130001 Major FLASHMAN0 no space event will occur.

With the new firmware, the amount of flash memory allocatable for the LDAP directory (that is, PBX config and call lists) is less than before to accommodate for the larger requirements. It is reduced from 3200kB to 2816kB on the IP800 and from 3200kB to 2560kB on the IP22/IP24/IP38/IP302/IP305.
