We have an asterisk server and a SIP provider for SIP termination. If I purchase a Digium TE110P card, do I need the SIP provider? Will the TE110P card act as the gateway? I would like to be able to find an alternative to the SIP provider. Sorry for such a newbie question!
Yes, you may use Digium cards to connect to a TDM provider as opposed to a SIP/VoIP provider.
