Es gibt seit kurzen wieder eine neue Firmware und anscheined nur eine Aenderung:
--- quote ---
SIP Multicast Negotiation Change
The Music On Hold feature now supports the new service parameter, Multicast
MOH Direction Attribute for SIP. This service parameter determines whether
Cisco Unified CallManager sets the direction attribute of the Session Description
Protocol (SDP) in its multicast Music on Hold (MOH) Invite message to sendOnly
or recvOnly.
When signaling multicast Music On Hold (MOH) to a SIP phone, the Cisco
Unified CallManager sends a direction attribute of ‘a=sendonly’. This follows the
RFC3264 guideline for signaling hold. Firmware release 8.5 (SIP) changes the
way to signal a multicast media participant to receive from a multicast address.
For additional information on this change, refer to RFC 3264, “Multicast
Streams”.
-- note ---
Cisco Unified CallManager signals ‘a=recvonly’ when indicating multicast MOH
to the phone. Firmware release 8.5 (SIP) changes the phone signalling to key off
of the receipt of a multicast ‘a=sendonly’ Session Description Protocol (SDP),
indicating a multicast MOH.
Cisco Unified CallManager modes refer to the ‘sendonly’ and’ recvonly’
attributes in the Service Parameters configuration. Cisco Unified CallManager 5.1
adds a new service parameter for the modes. The phone accepts both modes for
multicast media; once all phone images are upgraded with Cisco CallManager
5.1, the default SDP mode is set to the new mode.
The following lists the changes for the SIP Multicast Negotiation Change:
• A warning appears when changing the service parameters
• A service parameter is added as an advanced parameter
Note It is necessary to upgrade the image or configure multicast mode to get MOH on
older images.
