Grandstream Software Exist?

Does there exist VoIP software for windows that will interoperate with Grandstream products?

Softphones!

Bob, there are VOIP "softphone" programs that will communicate with VOIP phones and PBXes.  Linphone is one, but there are many more.

Hope that helps

Thanks!  I have tried Linphone without success,  What syntax is used to call from Linphone to a Grandsteam box, and vice-versa

PBX Config

Bob, the Linphone has to have an account/extension on the Grandstream PBX ahead of time.   That account info is used by Linphone to 'register' with the PBX.  Then the Linphone can call other extensions (and conference bridges, etc) on the PBX.
Linphone, like a VOIP phone, can be used to dial other VOIP phones by direct IP dialing too.

soft phones and Grandsteam

Thanks Orv.  In our case there is no PBX and all calls are made by direct IP dialing.
But so far it is not working.  In Linphone, I use the syntax sip:(IP address of Grandsteam phone).
But nothing happens.  Is that the correct syntax?

Troubleshooting

Just to be sure - each phone/computer is pingable from the other end?
And you use the * as the decimal point between the addresses?

Troubleshooting

Orv thanks very much for your encouragement. It is now working!
I went thru all my mess of test connections again and made sure I could ping.
Suddenly I could call from my PC with Linphone on one node to the Grandstream phone on another node.
Calling from the Grandstream does require the * for period, but calling from Linphone, it does not recognize
the *, but .  works fine.
