DGW Release Notes v2.0.37.697

IN 12159

During a call with a second peer (second call), when a SIP BYE is sent by the peer, two behaviors can occur depending on the value of the new EpServ.DefaultSecondCallDisconnectAction and EpServ.EpSpecificSecondCallTable.DisconnectAction parameters. If the parameters are set to

• Wait: the end of call tone is played and the next action depends on the user. This is the default behavior.
• AutoSwitch: a tone is played and the call automatically passes to the first peer.

Add CWMP parameters for all supported voice/data codecs which include G.711 a-Law, G.711 u-Law, G.726 16Kbps, G.726 24Kbps, G.726 32Kbps, G.726 40Kbps, G.729, T.38, clear mode, clear channel and X-CCD.

The CWMP parameters for hold, call waiting, second call, transfer, conference, forward telephony services, and DTMF map configuration were added.

It is possible to update the unit using a single file upgrade download. The multiple file firmware download is still possible.

The following parameters used to configure multiple file transfer for firmware upgrades are now deprecated:

• Fpu.MfpSelection.Index
• Fpu.MfpSelection.MfpName
• Fpu.MfpVersion
• Fpu.MfpLocation
• Fpu.MfpTransferProtocol
• Fpu.MfpHostname

The parameter Fpu.MfpUrl used to configure single file updates for firmware upgrades should be used instead.

Bandwidth control is now available on the Mediatrix Sentinel 400.

IN 11370

All parameters under Mipt.Codec group are supported in CWMP.

The parameters under the following groups are now supported in CWMP:

• EpServ.Hold
• EpServ.CallWaiting
• EpServ.SecondCall
• EpServ.Transfer
• EpServ.Conference
• EpServ.Forward
• EpServ.DtmfMap

The Sbc.NbActiveCalls parameter is now supported.

Fix memory leak upon reception of HTTP requests.

Fixed memory leak in DHCP client.

Single file update is now supported by DGW for firware upgrade. Parameters used to configure multiple file transfer for firmware upgrades are now deprecated. The parameter used to configure single file updates for firmware upgrades should be used instead.

SNMP's IfTable now contains the proper physical address for each interface of the unit.

Using the "Cancel Sensing" button in the ISDN/Status and EAM/Status Web pages had no effect. The "Cancel Sensing" button in the "Automatic Configuration" group of the ISDN/Status and EAM/Status Web pages is now enabled.

It was not possible to change the clock reference directly from Slot3/E1T1 to Slot2/E1T1. An intermediary setting had to be used to make it work. For example, from Slot3/E1T1 to none then from none to Slot2/E1T1. It is now possible to directly change the clock reference from Slot3/E1T1 to Slot2/E1T1.

IN 12298

If the DHCP server on the Mediatrix gateway was activated and configured with a subnet that is larger than 24, it would revert back to 24 when validating the range. Therefore, only the first 256 addresses from a subnet where usable in the range, even when the subnet was larger. Subnets larger that 24 are now handled properly by the DHCP service.

IN 12283

On an incoming call, the Sentinel FXO port did not always detect the ring and would not answer the call until the Pots service was restarted. The FXO port now properly detects the ring. The interrupt controller was fixed to prevent interruption losses that caused the FXO port to stop working.

IN 12272

TAC traces will now be published provided that they are enabled in Nlm service and that either the value for the Remote Host is not empty or that CLI logs are enabled.

The system installed on the unit needed an additional module to support bandwidth control. This module was added.

The unit sometimes fell in a state where it ignored the received LLDP-MED packets until the unit was restarted. The unit would therefore use locally configured network policies instead of applying the received policies. The restart logic of the LLDP service was fixed to accept LLDP-MED packets when a service is restarted.

IN 10280

Receiving a command from the ACS that contains a change that requires to restart the SipEp service and to refresh the registration no longer causes the system to close unexpectedly.

The SBC Number of Active Calls parameter is now supported.

In a SIP authentication scenario, the Sbc changes SRTP to RTP causing the remote peer to reject calls because of an "Unsupported type Media" error.

After downgrading the Dgw software from version 35.657 to a previous version, the "Running Config" page is empty. This is caused by the "Reset dialog by 1xx replies" Ruleset action.

Before downgrading, delete the "Reset dialog by 1xx replies" Ruleset action.
