We are looking for a provider who is able to provide us this kind of functionnality:
We are using a server who is able to make SIP call only
We would have several SIP account at this provider
For each SIP account, we could set an auto-callforward to a specific PSTN number
We have found providers giving us the possibility to set a Call Forward when the DID is called, but this call forward doesn't apply to SIP calls.
Do you have any provider who could let us do that? Otherwise, do you see any other solution to our problem?
Your help is greatly appreciated!
