dialer - Prepend phone numbers with a calling card dial in number

I use a calling card to call my home country and usually it's these steps:

1. Call the dial in number for the calling card company (e.g. 1 800 123 1234)


2. Enter the card PIN code (e.g. 1234 1234 1234)


3. Enter the destination number (which is saved as a phone in the contacts - e.g. +7 12 123456780)

I have several several contacts I call regularly and also plenty of one-offs.

Is there an app or way to automatically prefix the numbers from steps 1 & 2 along with pauses (p) and waits (w) so that I could dial the contact directly from the address book?

Thank you!

You might want to take a look at Prefixer, which lets you "prefix, suffix and/or replace numbers in your calls" -- sounds like exactly what you need. There are a few similar apps on the Playstore:

I'm pretty sure one of them will solve your issue.
