Analog
No a digital only phone will not work with analog service, but there are analog/digital phones, I don't know if these are still offered but they were very popular because during the transition from analog to digital, digital coverage was not as good as analog so when you had no digital service it would switch to analog. so the only way to have analog service is if the phone is dual analog/digital or if you have a old analog only phone. you can always look up your phone to see if analog is supported.
There is no way to get an analog phone to work on the new digital systems. They simply are not compatible.
If you are referring to the traditional PSTN phone, the signals that it receives are analog. If you want to know about VOIP phone, it is digital in nature. However, analog can be converted to digital by using a device called ATA.
Digital phone signifies the dialing method in a particular phone. The dialing method can be digital or analog. The house phone can be digital, where you press buttons to dial a number or in rare case analog type where in you turn a number on a dial. All cell phones are digital.
Internet phone conforms to Internet protocol. Analog phone can work with digital line by connecting a ATA into it. ATA is a connector or device that will convert analog signal to digital signal making standard phone an IP phone.

An DAC convert digital signal to analog signal i.e Digital to Analog Converter. An ADC convert analog signal to digital signal i.e Analog to Digital Converter.
Yes there will be no problems with this system.
A digital input (in the form of a number) is converted into analog format, which could be a voltage or a signal frequency, for example. An example, which most people would be familiar with, is your touch tone phone. When you press a key on the phone, that is a digital input. The output is actually 2 frequencies mixed together (analog signal). Each row of keys on your phone is associated with a frequency, and then each column of keys is associated with a frequency. The two frequencies combined represent the row and column of the key that was pressed. At the phone company, they use analog filters to determine what frequencies were generated by your phone, and from that, determine which key was pressed (this is Analog to Digital conversion).
Digital phones are more secure, can send both voice and data transmission, and has better sound quality. Analog phones are less expensive and only transmit voice.

In an analog phone, the mechanical energy of sound (speech) is picked up by a microphone (mic) and converted into an (analog) electrical signal. This signal is then put through whatever electronics stages are required (if any) to get the signal onto a phone pair for transmission to the receiver. In a digital cell phone, the mic picks up the sound and converts that into an analog electrical signal. That analog signal is then sent to an electrical stage called an analog-to-digital (A to D) converter. Once the signal is digitized, it can be treated as a data string and amplified and broadcast (to the cell hub) as such. An incoming call is a digital data string that is D to A converted in the phone and then the newly recovered analog signal is made to be heard by the user. The difference between the two is the conversion and re-conversion (analog to digital and digital to analog) in the digital cell phone.
