What we notice, is that some questions are more common than others. We thought we’d take a few minutes to give a quick run-down of some of our most commonly asked communications questions, to help you out of any potential VoIP pickles!

Issues making or receiving calls.

Problems with receiving or transferring calls is probably one of our most asked support questions, but can often be solved by changing one relatively simple setting on your internet router – disabling SIP ALG.

SIP ALG (Session Initiation Protocol Application Layer Gateway!) is a setting on many routers that is designed to prevent problems for VoIP traffic that can be caused by firewalls. However, although designed to help VoIP traffic, it almost always causes problems it is meant to help solve like:

  • Stopping phones registering
  • Blocking incoming calls
  • Blocking internal call transfers or internal calls

SIP ALG can be disabled on most routers, solving problems with receiving and transferring calls. If you’re not sure how to change settings on your router, your VoIP provider or ISP will be able to help!
