IAX to SIP Migration Process
Step 1 – Asses your current system setup
The majority of systems/PBXs that have been configured for IAX will also have the ability to utilise SIP. However, we recommend checking this before making any plans to migrate your service.
Step 2 – Configuring your Network for SIP calls
As IAX only requires port 4569 to be open, the network which contains your system will need to allow for additional ports and IPs.
VoIP Gateway IP Ranges
77.240.61.165/27
77.240.56.34/27
Proxy Domains and IP Addresses
voiptalk.org (77.240.48.94)
draytel.org (185.158.58.194)
If your router allows you to, we strongly recommend whitelisting our NAT Proxy domains and the domain you use to register against our gateway.
NAT Proxy Domains and IP Addresses
nat.voiptalk.org (77.240.48.201)
nat.draytel.org (185.158.58.201)
SIP and RTP traffic will traverse through these ports:
SIP Ports (5060 - 5065), UDP Protocol
RTP Ports (10000 - 40000), UDP Protocol
We strongly recommend configuring your network to allow traffic on these ports, but only from the IP ranges mentioned above.
Step 3 - Testing connectivity and registrations via a Soft Phone
Once your network is allowing our IPs and the port ranges, we recommend connecting a softphone to your SIP trunk to check that your network can successfully allow calls out and receive calls in as well.

In your chosen Soft Phone’s configuration menu, there should be an option to define a SIP Server, SIP Registrar or SIP Domain value. Set the value to: voiptalk.org.
For SIP Authentication, set your SIP User ID or similar to your VoIPtalk ID (eg 84411076) and set the Password to what has been set on the VoIPTalk Portal.
If you have an Outbound Proxy or SIP Proxy setting, set this to: nat.voiptalk.org:5065. If this setting allows you to define the port in a separate field, set the IP Address to: nat.voiptalk.org and the port number to: 5065.
Save all settings just made on the soft phone and check within the application that the registration to your trunk was successful.
Step 4 – Apply SIP configuration to the live system
Upon a successful test via the Softphone. The same SIP configuration can now be applied to your system which was previously configured for IAX.
You will need the same SIP domain and proxy:
- voiptalk.org & nat.voiptalk.org
as well as the SIP User ID and password:
- on the VoIPTalk portal. Instructions to find your SIP trunk’s password is detailed in the section below.
Please see below for details on obtaining your SIP trunk details through the VoIPTalk portal.
Obtaining your Trunk details via the VoIPTalk portal
Login to your VoIPTalk Account - https://www.voiptalk.org/
You will then be taken to your voiptalk account dashboard which will display your Trunk IDs. Click on the Trunk ID to open up a new window (make sure to allow pop ups on your browser if prompted), this window will display the Trunk ID, as well as the password, and will also allow you to change the password if required.
