Setting up a SIP trunk for outbound calling is essential for any PBX system, including Asterisk. With TelecomsXChange (TCXC), you can easily interconnect with multiple carriers around the world, including Airtel, TATA, Telin, and many more. Here's how to retrieve TATA Communications wholesale voice rates via API.
To begin with, authentication of PPW SIP traffic is done by source IP address on our platform. After adding your gateway IP addresses to your allowed list through the TCXC portal, you can establish a SIP trunk with our proxy servers (sip01.telecomsxchange.com, port 5060).
On open-source applications such as Asterisk, you can set up your SIP trunk by following these steps:
- Create a peer type with the following configuration:
type=peer qualify=yes progressinband=never port=5060 nat=yes insecure=port,invite ignoresdpversion=yes host=188.8.131.52 dtmfmode=rfc2833 disallow=all context=from-trunk allow=g729&g711&g723
No SIP registration is required against our platform.
It is highly recommended to use a graphical user interface (GUI) for Asterisk. Download and install any of the following GUI interfaces to simplify installation and make changes to most aspects of Asterisk via a web interface:
For other types of switch platforms, follow your vendor guidelines for configuring your switch (see Appendix).
Please note that we do not provide direct technical support for customer PPW switch platforms.
Now that you've set up your SIP trunk for outbound calling, you can take advantage of TelecomsXChange services to interconnect with multiple carriers around the world, including Airtel, TATA, Telin, and many more. With our platform, you can purchase with confidence, negotiate directly with sellers for better rates, quality, and/or service, and capture a SIP trace of outbound calls. You can also access all carrier rates for voice, SMS, and DIDs using our RESTful API and sync rates daily from multiple carriers to build machine learning (ML) applications and charts that are useful in the future.
