I have been testing your software, but skype policies do not allow more than 50 calls per day… We already have a t1 line in place. Would your software work with the t1 line.
If you are testing release 7, there is no need to go with Skype.
If you have a T1 line in place for voice calls, you normally already have a PBX system setup. If your PBX system is SIP compatible, meaning it supports softphone as an extension, then you can configure Voicent software to use your PBX system.
If your T1 line is a data line for your internet connection, you can signup a SIP based VOIP service provider.
