Version 2.1.1

• SIP part of the program has undergone significant changes. Correct and stable SIP registration is now supported. Fax Voip was successfully tested for the stable operation with a large number of t38 SIP providers directly. Now Fax Voip program accepts incoming fax calls without problems. You can use Fax Voip as an extension to the SIP PBX. There is no need to provide a static route for incoming calls. No problems with the Outbound Proxy feature as well.
• It is now possible to save incoming faxes directly in TIFF or PDF files. Fax Voip can redirect all incoming t38 fax calls in TIFF or PDF files without using a standard fax software, and without limiting the number of incoming fax sessions. In this mode, the virtual modem lines are not involved and can be used for outgoing t38 fax calls. It was designed and implemented a special software for the convenience of handling incoming faxes: FaxVoip Log Book.

Version 1.1.3

• Added support for G723.1 codec and GSM 06.10 codec. T38 is a special fax protocol for sending faxes over voip. But it is impossible to start calls without voice codecs. If your SIP provider does not support G711 codec, you can use G723 or GSM codecs. Now you can select voice codecs in the Fax Voip FaxModem Control panel.
• Added support for STUN server. It is very important feature for using with some SIP providers. Now you can enter STUN server name in the Fax Voip FaxModem Control panel.
• Fixed some errors in using Outbound Proxy. This feature is correct now.
  Added some comments about using Fax Voip with AXON PBX, as for incoming fax calls from external SIP Network to Fax Voip. If you have problems with incoming faxes, it is important to check Use static IP address and static mapped ports option in AXON PBX in the Network Settings panel and enter External SIP port and External RTP port starting from... values. No need to enter your Public IP address here.
