I have a UC560 that is running 8.6.1 and we have a PRI connected as the only phone line. Our PRI provider will not let us send a caller id phone number that is not in their system so when we have a SNR call it shows up as our main number on the cell phone. I am looking to get a SIP connection to allow me to do this and send the original caller id to the cell phone on a SNR call. I have setup Skype for SIP and it does not send the correct caller id.
Does anyone use a SIP provider that the SNR caller id works?
I personally do not know of a specific SIP provider that I could recommend. But there are some out there that validate the call based on the IP address it is coming from and not the Caller-ID/Account number.
Maybe someone else here may know of a provider they could suggest.
