Conference call number and code in email on iOS 7

Question

I get emails inviting me to a conference call which typically has a 1-800 telephone number followed by a few lines later for the participant code.
e.g.,
Dial in:  1-866-123-xxxxx
Host Code:  123484xx
Participant Code:  237284xx
If this info were in the iPhone's calendar invite, I know there are apps like Tempo in the App Store that can parse calendar invites and give you the option to dial: 
Host:  1-866-123-xxxxx,,123484xx  or
Participant:  1-866-123-xxxxx,,237284xx
What's the solution for email?  The iPhone recognizes  1-866-123-xxxxx as a dialable number, but how do I get the Code pasted?  I've tried copying and pasting the Code but there's no place to paste it in after the call is in progress.
Is the only workaround to copy paste into a calendar invite and then use Tempo to figure it out?

Answer 1

Check Settings App > General > Text size to see if the slider has been moved one way or the other.
Try a reset: Simultaneously hold down the Home and On buttons until the device shuts down. Ignore the off slider if it appears. Once shut down is complete, if it doesn't restart on it own, turn the device back on using the On button. In some cases it also helps to double click the Home button and close all apps BEFORE doing the reset.
