FAQ

Q:Does SessionTalk allow me to call Skype users?

A: No, SessionTalk iPhone Edition is a SIP softphone client. Skype uses a proprietary protocol for its VoIP communication. SessionTalk iPhone can make VoIP calls to anyone using a SIP compliant provider.

 

Q:How can I make VoIP calls over the 3G network?

A: If you have a data plan with your cellular network operator you can make VoIP calls over 3G/EDGE. The SessionTalk iPhone client will automatically register with your provider over the cellular network if a WiFi connection is not available. Note that a GPRS connection is not suitable for VoIP calls as the data rate is too slow. You can determine whether you have a 3G/EDGE connection as the status bar on the iPhone will either have the 3G or E symbol. GPRS is represented by a little circle. iPod users can only make calls over WiFi.

 

Q:Which codecs do you support?

A: Currently SessionTalk iPhone supports the G711u, G711a, GSM and iLBC codecs. We plan to support G729 and G722 in a future update.

 

Q:How much do you charge for VoIP calls?

A: SessionTalk iPhone is purely a SIP client. It is not tied to any VoIP provider. F-ROUTE Ltd is not a VoIP provider. To use the SessionTalk iPhone SIP client you need to set up an account with a SIP VoIP provider.

 

Q:What languages do you support?

A: English,French,German, Spanish and Japanese. More languages will be supported in future updates.

 

Q:The volume for the keypad button presses is too loud, how do i lower it?

A: The keypad button volume follows the ringer volume, simply lower the ringer volume using the volume buttons on the side of the iPhone.

 

Q:Regarding the Push option, will i just get a notification or will I be able to answer the call?

A: You will be able to answer the call by clicking on the answer button. SessionTalk iPhone is then launched and the call will be automatically accepted. After this, there is then no difference between a 'Push' call and a normal inbound call.

 

Q: Why is the 'Incoming call with Push' option grayed out sometimes?

A: If you have Keep Awake mode set as 'Always' this keeps the app awake even in the background and so allows you to receive calls without registering for Push. Thus the Push option is disabled in this mode. To re-enable it set 'Keep Awake Mode' to 'Off' or 'Foreground'. Please be aware that keeping the app awake in the background can drain the battery so this option is best used when on Mains power. The Push option will not affect battery life.
