3.1 What's New in Version 2.6.2
Version 2.6.2 is the first General Availability (GA) Version of MP-20x Rev B and is based on
Version 2.6.1. The following three MP-20x Rev B models are supported in this version:
•
MP-201 Rev B, providing one FXS interface
•
MP-202 Rev B, providing two FXS interfaces
•
MP-204 Rev B, providing four FXS interfaces
Version 2.6.2 supports only MP-20x Rev B devices. The next version – 2.6.3 – will be the first GA
version to support both Rev A and Rev B devices.
Dual firmware image support on 8-MB flash devices: MP-20x Rev B models provide an increased
flash memory of 8 MB, which is capable of storing two firmware images (the primary image and a
recovery image, described below). For previous MP-20x devices, which provide only 4 MB of flash
memory, a separate Version 2.6.2 firmware file is available.
Recovery firmware support: In addition to the primary firmware, the MP-20x stores a recovery
firmware, which is executed only if the primary image is missing or damaged (e.g. if the user
unplugs the power during firmware upgrade). Except for the analog or VoIP interfaces, the
recovery image supports all other interfaces and enables the MP-20x to reconnect to the Internet
and download the primary firmware.
3.2 Resolved Constraints in Version 2.6.2
The following bugs were resolved in Version 2.6.2:
When pressing 'Flash' + '1' or 'Flash' + '2' (for call hold and transfer), the DTMF signal is
sometimes audible at the remote side.
When the key sequence is set to "flash + digits sequence", only one-way voice occurs in blind
transfer.
When the key sequence is set to "flash + digits sequence", a warning tone is heard after transfer
and semi-attended transfer.
When the key sequence is set to "flash + digits sequence", a warning tone is heard after returning
to the first call when the second call is not answered.
When the key sequence is set to "flash + digits sequence", a warning tone is not heard upon an
unanswered call.
3.3 Known Limitations in Version 2.6.2
Version 2.6.2 includes the following known limitations:
Three-way conferencing with local mixing is currently not supported on MP-204 Rev B devices.
This feature will be added in Version 2.6.2 for some hardware versions.
Faxes can only be sent between two local lines if the selected fax transport mode is Transparent
(in G.711).
The Web interface is not automatically refreshed during the firmware upgrade process.
After the dial tone timeout has expired (and a fast-busy tone is played), the user can still make an
