FAQ
Where can I download the PortSIP VoIP SDK for testing?
You can download the PortSIP VoIP SDK and sample projects from the PortSIP Website.
What Android API version is required?
The PortSIP VoIP SDK requires Android API version 16 or later.
How can I create a new project with the PortSIP VoIP SDK?
Download the Sample Project and SDK: Obtain the sample project and trial SDK from the PortSIP Website and extract them to a desired directory.
Create a New Project: In Android Studio, create a new Android Application project.
Add the SDK Libraries: Copy all files from the
libsdirectory of the extracted SDK to thelibsdirectory of your new application.Import Necessary Classes: Import the required classes from the SDK:
How can I process callback events?
Implement the OnPortSIPEvent Interface: Your class should implement the
OnPortSIPEventinterface to handle callback events.Override Callback Methods: Override the necessary callback methods (e.g.,
onRegistrationState,onCallState) to handle specific events.
How do I initialize the SDK?
Create an Instance: Create an instance of the
PortSipSdkclass.Set the Event Listener: Set the event listener using
setOnPortSIPEvent.Create a Call Manager: Create a call manager using
CreateCallManager.Initialize the SDK: Call the
initializemethod with appropriate parameters.
Is the SDK thread-safe?
Yes, the PortSIP SDK is thread-safe. You can call API functions from multiple threads without worrying about synchronization issues. However, there are exceptions: the onAudioRawCallback, onVideoRawCallback, and onRTPPacketCallback callbacks should not be called directly from other threads.

Returns
If the function succeeds, it will return value 0. If the function fails, it will return a specific error code.

This function allows to periodically refresh Session Initiation Protocol (SIP) sessions by
sending repeated INVITE requests.
Parameters
timerSeconds

Returns
If the function succeeds, it will return value 0. If the function fails, it will return a specific error code.
Remarks
The repeated INVITE requests, or re-INVITEs, are sent during an active call log to allow user agents (UA) or proxies to determine the status of a SIP session. Without this keep-alive mechanism, proxies that remember incoming and outgoing requests (stateful proxies) may continue to retain call state in vain. If a UA fails to send a BYE message at the end of a session, or if the BYE message is lost due to network problems, a stateful proxy will not know that the session has ended. The re-INVITES ensure that active sessions stay active and completed sessions are terminated.
Disable the session timer.
Enable/disable the "Do not disturb" status.
Parameters
state

If the function succeeds, it will return value 0. If the function fails, it will return a specific error code.
Enable or disable to send SIP keep-alive packet.
Parameters
keepAliveTime
This is the time interval for SIP keep-alive, in seconds. When it is set to 0, the SIP keep-alive will be disabled. Recommended value is 30 or 50.
Returns
If the function succeeds, it will return value 0. If the function fails, it will return a specific error code.
Set the audio capture sample, which will be present in the SDP of INVITE and 200 OK message as "ptime and "maxptime" attribute.
Parameters
ptime
It should be a multiple of 10 between 10 - 60 (included 10 and 60).

Set the SDK to receive SIP messages that include special mime type.
Parameters
methodName
Method name of the SIP message, such as INVITE, OPTION, INFO, MESSAGE, UPDATE, ACK etc. For more details please refer to RFC3261.
mimeType
The mime type of SIP message.
subMimeType
The sub mime type of SIP message.
Returns
If the function succeeds, it will return value 0. If the function fails, it will return a specific error code.
Remarks
In default, PortSIP VoIP SDK supports media types (mime types) included in the below incoming SIP messages:
"message/sipfrag" in NOTIFY message.
"application/simple-message-summary" in NOTIFY message.
"text/plain" in MESSAGE message. "application/dtmf-relay" in INFO message. "application/media_control+xml" in INFO message.
The SDK allows to receive SIP messages that include above mime types. Now if remote side send an INFO SIP message with its "Content-Type" header value "text/plain", SDK will reject this INFO message, because "text/plain" of INFO message is not included in the default type list. How should we enable the SDK to receive SIP INFO messages that include "text/plain" mime type? The answer is addSupportedMimyType:
addSupportedMimeType("INFO", "text", "plain");
If the user wishes to receive the NOTIFY message with "application/media_control+xml", it should be set as below:
addSupportedMimeType("NOTIFY", "application", "media_control+xml");
For more details about the mime type, please visit: http://www.iana.org/assignments/media-types/
