Release Notes for firmware version 4.07

Change Log

The Annuncicom may now receive audio on a Multicast address. The Multicast IP Address is configured via the WEB UI.

An improved audio buffer management aids the fine tuning of latency. A value of 40 msecs is achievable: PCM 24kHz, sender packet size 480 bytes, receiver play buffer size 480 bytes.
PCM audio encoding is no longer supported in TCP mode.
The “loop Input to Output” audio volume is fixed.
Switching to decoding mode requires an additional 200 msecs. Any audio received during this period is discarded.

Some minor corrections to the WEB UI look and feel.
On IPAM102 devices, corrected outgoing PCM audio formatted UDP streams stored in even table entries which were distorted.
DHCP will now automatically renew after losing connection to the DHCP server. A new DHCP address should be assigned (and the device will reset) within 5 minutes.
Handling of lost segments corrected, providing a massive improvement in lost packet retransmissions.
A problem fixed which caused the Exstreamer 110 HW revision 1.4 to reset. Note: When loading the Annuncicom SW in an Exstreamer 110, the functionality is not guaranteed.

Annuncicom 200 SUB Aiphone Use - Releasing the “Press to Talk” button does not stop the audio stream.
Exstreamer 110 Use - If the Exstreamer 110 is left in the default settings of Audio: MPEG and Streaming mode: send on Talk, commands sent to the device may cause a reset. For example, setting the Relay. Work around: When using an Exstreamer 110 always set the Streaming mode to “receive only”.
For IPAM102/302 devices PCM audio encoding is no longer supported in TCP mode.
