The service offered free calls between SIPSERVICE users. In addition it offered fee-based calling packages for calls to domestic and international destinations. The service was supported by user accounts on an online portal that assigns free geographical phone numbers. Users were able to use any Session Initiation Protocol (SIP) client software, SIP analog telephony adapter (ATA), or hardware SIP phones with the service. SIP phones and other associated hardware from a variety of manufacturers were available for sale at the sipgate web site. Since January 2009 SIPSERVICE provided their customers short message services (SMS) through their website. Users have been able to set the originating phone number to be that of their mobile phone.
