STIR/SHAKEN SIP headers support and more..

A few important updates will land to TCXC production environment today.


TelecomsXChange (TCXC) is now officially registered in the Federal Communications Commission Robocall Mitigation Database holding number RMD0004338. We have already added the support for the STIR/SHAKEN required SIP headers last week. We have also exposed some UI/API tools for sellers to help them take action in real-time to stop/mitigate any suspicious traffic.

The new SIP Identity headers required by STIR/SHAKEN are now added to TCXC SIP stack. All members are welcome to start testing.

New CLID (Caller ID) policy for sellers

We have released a new policy for sellers which enable them to have full control over the CLID policy to be used for each SIP connection (route). For instance a seller can now define a default Deny all caller ids except defined entries in the table, this can come in handy for virtual number providers who wish to offer a local sip trunk but at same time allow it only to be used from DIDs that are sold via the platform.

While data centre connectivity issues are rare, layering your connectivity to our geographically isolated servers will ensure that you ride the rare glitches without even feeling it.

Softswitch on AWS now available

Moving your Softswitch to the Cloud is easier and more important than ever

For many years, communications service providers (CSPs) have been installing, hosting, and operating VoIP Softswitches on bare metal servers. Even when Amazon AWS cloud got popular, yet many communication service providers could not benefit from what the cloud has to offer due to the nature of Voice Over IP (VoIP) traffic. Here is an example of the 7 best benefits that AWS Cloud provides its users that telcos not hosted on AWS are missing today.

From my experience, one of the obvious issues for soft switches and RTP software playing not so well with AWS Cloud out of the box is the Elastic IP Architecture. An Elastic IP address is a reserved public IP address that you can assign to any EC2 instance in a particular region until you choose to release it.

Communications RFP process digital transformation


Realtime communications like voice, SMS, Phone Numbers is now a part of modern applications across all industries, from small startups to unicorns use communications APIs in their workflows.

App developers are focused on developing and serving their main business customers, as they grew they have realized that that communication services like 2FA / SMS, Voice, Virtual numbers are a critical component of their business today and there is a lot of recurring cost involved with having these communication components as part of their application user experience.

The Problem

As traffic grows companies start issuing RFPs every monthly, quarterly or annually with total amount of minutes, messages, numbers per destination/network they consume and share it with communication service providers bid on it. This RFP process is manual and unpleasant for the most part for communication providers who is bidding, it also takes a long time for the app developer to switch traffic to a lower cost provider since the RFP process is still in process or incomplete.

For those who come from the telecom industry know that prices and quality are dynamic and they several times a week, being stuck with a single provider for a long time is no good for the company.
