In some cases where collect calls are needed, e.g. calls from prison inmates, there are additional restrictions that may force you to have a conventional landline. If that's your situation, you might consider:
1. A "lifeline", "low-use", or measured landline.
2. A landline number that remote-call-forwards to GV or other service that you have.
3. A good friend with a landline and three-way calling receives the call, accepts the charges and puts you on the line.
4. A service such as

Otherwise, please provide as much detail as possible (why a toll-free won't work, etc.)
