SIP Stun and SIP Stun Server: If your iSip is behind a NAT/Firewall and your Sip Provider does not do RTP proxy, you'll likely need a stun server so that your voice traffic can go through the NAT.

CODEC: See answer to question 11

Outbound Proxy: If you want iSip to make SIP calls through a proxy, set it here. the format is like this: "sip-proxy-domain-or-ip:port". You do not have to specify the ':port' portion if your proxy uses the default sip port 5060.

RTP Port: Tell iSip your local RTP port preference. For example, if setting it to 12000, the local RTP port used by iSip in any SIP call will always be greater than 12000.

VAD: VAD = Voice Activity Detection.RTP Silence Suppression Endpoints sending audio as an RTP stream are not required to send packets during silent periods. The capability to stop sending RTP packets during silent periods is known as "Silence Suppression" or VAD (Voice Activity Detection). Whether to use Silence Suppression is usually a configuration option on endpoints. When processing a stream of RTP packets, here is what RFC 3389 has to say about detecting Silence Suppression: RTP allows discontinuous transmission (silence suppression) on any audio payload format. The receiver can detect silence suppression on the first packet received after the silence by observing that the RTP timestamp is not contiguous with the end of the interval covered by the previous packet even though the RTP sequence number has incremented only by one. The RTP marker bit is also normally set on such a packet.

RFC3605 Support:disable this to compatiable with legancy sip server.The Session Description Protocol (SDP) is used to describe the parameters of media streams used in multimedia sessions. When a session requires multiple ports, SDP assumes that these ports have consecutive numbers. However, when the session crosses a network address translation device that also uses port mapping, the ordering of ports can be destroyed by the translation. To handle this, we propose an extension attribute to SDP.

Tap 'Play' button, It will list the audio you record during calling.you can select them to check.Look at the following page:



 

Prefix for Contacts: you can specify a 'prefix-number' so when you make a call directly from one of your stored contacts, iSip will automatically add the 'prefix-number' to the stored number when dialing

Tap 'Deault Ringtone' ,you will get to the following pag,and set a default ringingtone for the new created sip account.

 



 

Tap 'Mic Volume',you can setup the Mic volume. The page as follow:



 

Dial Setting:You can enable or disnable Cellular Dialer .But if the device you use is iTouch,it doesnot have this function.For example,if you disable it,you will see the 'Cellular' button is disnable.the page as follow:




 

Tap 'Reset',you can go to the following page to reset:



 

Reset Account:If you tap it,It will delete all sip accounts. And the sip accounts will be same as default.
Reset Setting:If you tap it,the setting will be same as default.
Reset Factory:If you tap this, It will delete all sip accounts and the setting will be same as default.

You can enable or disable the ring or vibrate when there is an incoming call. But if you are using a iTouch,it should show you the following page:

 



 

Tap 'Background Photo', you can select image for the background,and you will see the following page:

Tap 'set' Button ,you will set it as a background photo successlly.And if you are dialing a call,you will see the image,for example:

 

Most cases you won't need to setup the stun server. But if you do, you can set it up via the settings page. Enable the 'Stun Server' settting and also specify the domain name/ip of the stun server. You need to restart the iSip application to let the setting take effect.

Most cases you don't need a SIP proxy for your SIP calls. But sometime the network environment you are in may require your SIP calls to go through a SIP proxy. To set it up, you can either add the proxy information through the 'Account Manager' to whichever account that requires a proxy, or you can set it up through the 'Settings' page which applies to all accounts.

They serve the same purpose as explained in the last question. The difference is, the proxy setting in the 'Account Editing' page applies only to that particular account, while the 'outbound proxy' in 'Settings' page applies to all the accounts.

In a word, only when all of your accounts require the same proxy, you need to set the 'outbound proxy' in 'Settings' page. For all the rest scenarios, you should leave it empty.
