I have a client using a hosted VOIP PBX solution. We need to be able to cause their SIP phones to call a specific external number, when selected in our application. For several reasons, we can't use the VOIP provider's normal click-to-dial feature. They suggested that we might be able to do an INVITE to connect to the phone, and then a REFER to do a blind transfer to the destination we want to call. I need a routine that can be called from my Visual Foxpro application (passing it the identification of the phone, and the number to dial). It will then do whatever is needed to connect to the PBX system, do the INVITE, possibly wait for the person to pick up their phone, and then do the REFER to cause that phone to connect to the external number. This will be in a multi-user,Remote Desktop environment, so it will need to be able to have several copies of the routine running on the same machine, in different user contexts. If you are familiar with SIP programming and would like to do a small project like this, or if you need more information, please let us know. Thank you.
