Sippy 2022 Release
Sippy Software Inc. is happy to announce our newest release will be available on February 14th, 2023. Updates to your production systems can now be scheduled with our support team if you have a valid support agreement and are on the latest version of our prior release. If you do not have a valid support agreement please contact firstname.lastname@example.org to purchase a support package for your system.
Account Trunk Enhancements
In prior versions we only had support for a main trunk connection and a backup trunk connection. We have made some major changes to how we manage trunk connections and it is now possible to support multiple trunk connections instead of just having a main and backup connections.
New Web Framework
To support some of the work needed for the multiple trunks we have also adopted a new web framework that will be used to improve usability of this feature as well as give us a starting point to improve the overall web user experience. We plan on extending this new framework to additional pages in our upcoming releases.
Improved Video Calling support
With the updated RTP Proxy included in our release it also comes with some improved video calling support. This is a useful feature to explore opportunities for doing video calls through your softswitch. A practical application of this feature for example would be home security cameras. You could set up a SIP based security camera to call the home/business owner and send the video call through as it picks up movement on the camera.
During our development cycle for Sippy 2022 we created a new solution that will allow users to create a safe, secure, and offsite backup solution. Your regularly scheduled backups will be automatically uploaded to an Amazon S3 bucket protected from any hardware problems that could happen at your Local Data Center. This solution is cheaper than a full standby system but effective enough to quickly rebuild your Softswitch with some of your business critical data. If you are interested in subscribing to this service contact our email@example.com for pricing and additional details.
GoLang version of RTP Cluster
In support of our efforts to work on a clustered version of our software we have worked on some changes to rewrite RTP Cluster into golang. RTP cluster is used to monitor and manage load between different RTP Proxy instances setup on different nodes.
In Sippy 2021 we added SIP TCP/TLS giving the infrastructure needed to extend SRTP functionality to the softswitch. This feature is also one of the last few improvements needed to extend the product to support Microsoft Teams integration in the future.
A number of improvements were done to our firewall system to better manage SIP TLS/TCP connections. We have made some important improvements for incoming SIP TLS/TCP connections for the firewall as well as added some improved support for TFTP and notifications. You can also now bypass a set of firewall rules for UDP traffic and speed up the processing of RTP data.
DID Ranges - A FreightSwitch Feature
We have added initial support for DID Ranges for Freightswitch that will allow Switch operator to manage larger ranges of DID numbers. Since DID Ranges can easily contain tens or hundreds of thousands of numbers, adding support for blocks of numbers makes a lot of sense to manage in a more effective way. We’ll be working on some additional changes for API and web interface changes at some point for Soft Switch in the future.

SS-5205 - Refactor OpenSIPS config for better structure and clarity
Some improvements were done on the backend side to improve how we interact and manipulate configuration parameters in OpenSIPS.
SS-5184 - Add per environment xmlapi control for hiding password settings
A per-environment setting has been added to control visibility into hiding or displaying vendor connection passwords.
SS-4998 - Add new firewall_type for tftp to manage access to service via web firewall tool
You can now manage tftp connections using the web firewall tool. If these are set to default values there is also a notification in the web user interface for you to review and update those.
SS-5120 - Change subject in Send by Email for DID and Vendor CDRs
It will now be a bit easier to tell the difference between Customer, Vendor and DID CDRs. We have adjusted the both subject headers to tell them apart.
SS-3214 - Call direction information can be retrieved from the B2BUA
We can now get call direction information about active calls from the b2bua.
SS-5437 - Media Port Change
In compliance with some new Turkish Regulations we have made a patch to ensure the media port remains consistent between when the call is first announced to when it is connected. This patch is available for all our production versions of our software upon request and is built in for Sippy 2022.
SS-5332 - Create a notification for web pages for legacy browsers
The changes for our web interface also means we no longer support Internet Explorer 11 and legacy versions of other browsers. We have added a notification when users are using legacy browsers informing them to update to the latest version of Chrome, Firefox, or Edge.
SS-5315 - Maximum call-id field length for related CDR tables
We have extended the length of characters that can be used for call_id from 128 to 256 characters.
SS-4935 - Add a DB setting for Thrift
Thrift file export can now be enabled via xmlapi. This is particularly useful for our AWS Cloud installations. Please contact our support team for help if you need to export this data out.
SS-4812 - Configurable Default Values for Follow Me Timeouts are now added to system wide configuration parameters
We made some changes to allow for a configurable default value for Follow Me timeouts. This should make it easier to specify this setting when you need it.
SS-1000 - Compress Data export files
Data exported (for example rates) is now compressed thanks to Apache. In our tests this means a 104 MB rate file is compressed down to a 34 MB file saving time in download. Compression can be disabled if CPU performance is an issue as downloads are performed however this should have a minimal impact overall.
SS-5146 - Update from Python 3.6 to Python 3.9
We’ve updated the python package to Python 3.9.
SS-5146 - Update PHP to 8.1
The version of PHP installed has been updated to 8.1

The Test Dial plan has now been updated to receive two new parameters in relation to privacy. pai_hdr and rpid_hdr can now be used as part of these api methods to reflect the username portion of SIP URI in P-Asserted-Identity and Remote-Party-ID headers respectively
SS-5314 - getDIDInfo() and getDIDList() XMLAPI does not return incoming_cli
We have corrected an issue where getDIDInfo() and getDIDList() were not returning incoming_cli.
SS-5463 - Remove IPs of former Kyiv office from firewall and hosts.allow
We have updated our whitelisted IP addresses and removed the IP addresses from our former Kyiv office. Contact our Support team for a list of whitelisted IP addresses.
SS-5305 - Backup with TAR format writes to root partition and fails

SS-5388 - DID cache reload
DID cache seemed to be reloading every 10 seconds. A fix was put into place that will now reload the cache when changes to the DIDs are made. This change has been applied to all our production versions.
SS-5377 - Bye from Vendor is not forwarded to Caller in TLS Scenario
For TLS calls when Sippy attempts to forward a BYE received from the Vendor to Caller to the destination of the Contact header Received in the INVITE a new TLS session is established to another port/IP address. This causes the BYE to be dropped with 477 error on OpenSIPS. This issue has been corrected. Thanks to Neil from Brightstar with the ample help in troubleshooting some of the problems from our initial TLS implementation.
SS-5358 - Fix warning for intermediate SSL Certificate of Starfield Technologies Inc.
