When configuring the key sequence style to "Send Flash Hook via SIP", the user can modify the
INFO message that is sent upon Flash. The user can change the following fields:
• Content Type header field
• Message Body field
For example:
• SIP INFO Header = application/broadsoft; version = 1.0
- or / and -
• SIP INFO Body = event flashhook
The update is performed in the 'Voice Over IP - Dialing' page, under the 'Key Sequence' group.
Disables the call waiting tone when in Fax mode.
4.2 Resolved Constraints in Version 2.6.1
The following bugs were fixed in Version 2.6.1:
MP-202 does not send a second REFER message after the first one is replied with a '401 Not
Authorized' SIP response.
Handling of re-INVITE messages cause memory 'leakage' – this was fixed by disabling the Session
version condition check.
MP-202 always sends 14400 as the bit rate in T.38 SIP messages.
MP-202 doesn't update the DSP after RFC 2833 SIP negotiation.
MP-202 can’t handle hold (inactive/sendonly) and codec changing in the same SIP INVITE
message.
A Reorder tone, indicating a registration error is played even if MP-202 doesn’t use a registrar (i.e.,
SIP proxy).
PRACK Disable does not function.
SIP messages from additional entities are blocked if the DST feature is enabled.
When “Connect on 180” is disabled and the MP-202 receives a 180 with SDP, the MP-202 doesn't
play a local dial tone.
