Sippy Switch v4.5 Release Notes
Sippy’s release notes are a summarized guide to help existing and prospective customers understand what is new and improved in the Sippy Softswitch product.
This release includes many new web API methods, continuing on our mission to to give Operators a switch that is 100% programmable.
Great effort has been put into improving switch performance. We have observed improved performance numbers on this new release, exceeding 11,000 concurrent calls with Call Per Second rates north of 500. Most of the performance gains are thanks to improved CDR write performance.
Web application improvements
Many small usability and consistency improvements have been completed on the web application.
Many more Web application features now use the web APIs, which means that Audit Logs are recorded for even more administrative tasks. We will soon have complete Audit Logging coverage for all administrative actions.
New graphs for Media/RTP activity have been added.
Audit Logging now covers most of the critical functions of the system, and database security has been improved.
WEB Application Changes
The layout of graphs has been re-organized into three columns instead of two, to make more room.
RTP graphs have been added to show RTP/Media session counts, throughput, and RTP health.

Environment Interface now uses the web API

Additionally, when an environment is stopped by an operator, all active calls will be forcibly terminated before the system stops. SS-1222, SS-1223, SS-1224, SS-1226, SS-1227, SS-1193
Environment Listing redesign
The Environment listing page now lists CPS and Sessions, and sums the total, making it easy for operators to see the allotted capacity by environment. The values are summed to display totals. If there is an environment with unlimited capacity, then then infinity symbol will display, and the total will also display as infinity. SS-1172
The Actions item on environments is now a drop down, and the naming of actions has been improved. SS-1322

SIP Header Pass through is now configurable by using the new web API system parameters web API methods. SS-1464. The web application will be update in a future release to allow configuration of same via the web application.
SIP Registrations to non-primary IP address
SIP user agents that register to a non primary IP address of a switch are now handled correctly when a new call is directed at that SIP user agents location. SS-1445
Value for Max Sessions on Accounts have been changed.
On an Account,
max_sessions = 0 will prevent any calls from passing.
max_sessions = -1 means that the Account session limit is Unlimited.
SS-1504, SS-1541 This change is invisible to all except API users that
create accounts via the API and set
max_sessions explicitly. The
max_sessions value is updated during the 4.5 upgrade procedure.

Several improvements and bug fixes have been made to the Minute Plans feature. SS-1543, SS-1518, SS-1631, SS-1142,
Final 2xx timeout on Routing Groups
Routing Groups have a new “Final 2xx timeout” feature that allows the switch operator to control the final timeout of a call that is being sent to a vendor. SS-1432.
It is now possible to set an upper limit on the number of Trusted CLI numbers of a CLI application. SS-1337
When a DNCL (Do Not Call List) match is found, the translated CDR will be written to the CDR table, which is shows the exact number that was matched by DNCL. SS-1685
A call disconnection issue where follow-me and onnet call are enabled has been fixed. SS-1578
setup_time value will now be identical across
cdrs_customers and calls table. SS-1494
When cost values evaluate to zero after rounding, ensure that the recorded
value is always
0 and never
Longer prefix matches in Destination sets now has higher precedence then shorter matches. SS-1431
2XX timeout records proper 180 code in CDR
When a 2XX timeout deadline is reached in Sippy, the resulting CDR will have the code 180 instead of 100. SS-1357
Transformation Rule delimiter.
Transformation Rules now support both semi-colons and commas as rule delimiters. SS-1340
DID CLD Translation Rule Feature
The DID entity has a new CLD Translation rule. This feature allows operators to route many DIDs to new numbers, and track all billing via one single account. SS-1316, SS-1326, SS-1325
DID Validation Improvements
DID validation now imposes the same rules as described in the SIP RFC. DIDs will automatically have any tabs or white space trimmed when saved. SS-1598
SQLCached has been improved to be more efficient, and as a result CDR writing to the database is much faster. This reduces Disk I/O load, and overall system load for busy switches, and significantly reduces the likelihood of systems experiencing “CDR Lag” where a CDR is not immediately visible in the database after a call has ended. SS-1123, SS-1610
If a systems b2bua ports are limited more than the ports configured in an environment, then the b2buas in new sub environments would fail to start. SS-1618, SS-1376
A database lock that was engaged during CDR table rotation has been removed, as it is no longer needed. This reduces CDR lag on busy systems during CDR partition rotation. Several other improvements have been made to the rotation procedure. SS-1615, SS-1408, SS-1407, SS-1041
Environment jails can only gain access to the associated environment database. SS-1595
SIP Indexer processes all environment logs in round-robin order
To prevent one or more busy environments from dominating the SIP Log Indexer, the Indexer now takes a round robin strategy to indexing batches of logs from each environment. This makes sure all environment logs get fair indexer time, and if system load causes the Indexer to lag, then the busy environments will experience Log Indexing lag, but other environments will not be disproportionately affected. SS-1392
Other / Miscellaneous
CPS limit on Account has been improved so that it is explicitly scoped to the Account, and does not affect the environment. SS-1614
The re-rate utility has received several improvements and fixes. SS-1501, SS-1498
Voice mail recording has been fixed when the calling UAC only presents G.729 as an available codec. Other improvements to voice mail handling have been implemented. SS-1364, SS-1208, SS-1209
