Profile Requirements
An Internet Telephony Service Provider (ITSP) or a third-party corporate-deployed server provides telephony services over the Internet. The service provider supplies the gateway to the PSTN network for a Windows CE-phone session or initiates a phone-phone call.
Sessions that use service providers or third-party servers require XML profiles. The force profile flag in the IRTCClient::CreateSession method specifies a profile for multiple service providers or messaging sessions with various profiles. The third-party corporate-deployed server is stored in the profile under the SIP server element. The ITSP is listed under the provider element.
Before these profiles are used, they need to be enabled and registered on the server with the IRTCClientProvisioning::EnableProfile method.
The following table shows a summary of the XML profile and ITSP requirements for each session type.
| Session type | Profile |
|---|---|
| Windows CE-SIP client | Specifies an outgoing proxy server or ITSP if one is used to set up the call. If the URI is an IP address or machine name, a profile is not required; a direct communication link is established. |
| Windows CE-phone | Required to locate the SIP proxy server and gateway. An ITSP or third-party server can be used to locate the gateway, or the gateway can be specified directly in the profile. |
| Phone-phone | Specifies an ITSP or third-party server that initiates the call. It also provides gateway information. |
