Rev. 1.00 12-02-13 12/41

does not send any final answer to the INVITE request. This is now corrected and SmartWare

sends in addition to the “200 OK” to the BYE also a “487 Request Terminated” answer in

response to the original INVITE request.

11891 SN4660/SN4670 Rev C and Rev D support

The new SmartWare build has now integrated support for the latest revisions of the

SN4660/SN4670 products.

11895 Ethernet switch problem on SN4660/SN4670

Two problems related to the Ethernet switch chip on SmartNodes 4660/4670 were fixed. The

bootloader was crashing when two network cables where connected. When Ethernet 0 and 1

where both connected to the same switch the IP routing would fail because the software did not

maintain separate MAC address tables for each port.

11898 Enhancement of software upgrade procedure

The software upgrade procedure in SmartWare is enhanced to support software deliveries

packed as tar files and the ability to upgrade in the future to a different Operating System.

11899 SIP Hold/Unhold behavior

When the SmartNode is set on hold with the SDP a=inactive during a SIP call, the SmartNode‟s

responding SDP would always be a=recvonly. The behavior was adjusted so that SmartNode

responds to a=inactive with a=inactive and to a=sendonly with a=recvonly. This behavior

change is needed to be compliant with Microsoft LYNC servers among others.

11902 SIP q-value of 1.0

The Q-value feature did not allow sending a maximal value of 1.0. Now it is possible to send all

values between 0.0 and 1.0.

11929 SN-DTA clock synchronization

On the SN-DTA device a problem related to ISDN clock synchronization has been fixed. It

occurred if an external TE device was configured to get its reference clock from the SN-DTA‟s

NT port. Especially if the connected device was a PBX which itself served FAX machines, the

problem resulted in failing FAX transmissions.

11932 SIP 503 error handling

SmartWare was not correctly hunting for SIP peers if a DNS lookup returned multiple A records.

In case the SmartWare SIP gateway receives a list of possible IP addresses it should try to

connect to the first IP address in that list. If this does not work due to a network problem or if the

peer SIP side sends a 503 Service Unavailable, the SmartWare should try the next IP in the list.

Now in one very specific case SmartWare received a 100 Trying between the initial INVITE and

the 503 and was therefore not further trying to connect to the next IP address. This behavior

has been changed to allow proper SIP destination hunting.
