I know that using the URL with tel:// I can launch the phone app to make a phone call, but I don't know how to do the phone call with the speaker turned on.
Thanks!
There is no API for that I'm afraid. The tell:// is all the 'access' you will get as far as the phone application goes.

Is it possible to call a phone number programmatically in iOS and send different DTMF tones during the call?.
Basically I want an App to handle the IVR call. I don't know anything about iOS programming. I just want to know the feasibility so that I will put further effort.
Thanks
You cannot do this interactively within the bounds of the iOS SDK (ie, in an App Store app).
You can, however, build a tel URL. See the Apple documentation on phone links for more details if you think this will work for your needs.
Is there anything like Telephony.SECRET_CODE in iOS? I need to open my application if international numbers are typed on phone dial pad?
I'm not sure what Telephony.SECRET_CODE is but you can't open an iOS app from the phone app.
Is there a way to place a standard call and when call is in progress to play some predefined voice?
For example, I want my app to automatically call someone at predefined time and then to play message I've recorded.
No, you cannot interfere with a customer's phone call. And Apple wouldn't approve this app for the app store if you submitted it.
I want to develop application to show user video or image when someone is calling me. I know it is possible on android, but i don't know about ios platform. Is it possible to do such an application ?
Apps can only modify things within their own sandbox. The incoming call screen, is part of the phone app and therefore can't be modified. The only way to do this would be on a jailbroken iPhone, and it would be quite difficult.
I am building an app in which I need to let the user dial a phone number. Looking through the documentation, I could not figure out how to do that. There is a module for SMS, but none for voice. Is it possible to make phone calls from your Trigger.io app?
Yes, you can use a tel: url, for example:
Phone 123
