If you are using a Hayes-compatible modem (with the AT* command set), this may help, depending on what you want.
If you want to change volume, use ATL#, where "#" is: 0 for low-volume, 1 is for slightly higher volume, 2 is medium, and 4 is high-volume.
To switch the speaker on and off, ATM# would be used, where "#" is: 0 for speaker off, 1 to turn the speaker on until it detects a carrier (usually used by default), 2 always keep the speaker on while the modem is off hook, or 3 to turn the speaker on until the carrier is detected, except for when actually dialing the number.

From what I understand, you just want to hear the dial, and nothing else (negotiation, etc...). I don't think this is possible for almost all modem, but I'm not sure.

speaker-test - command-line speaker test tone generator for ALSA SYNOPSIS
speaker-test [-options] DESCRIPTION
speaker-test generates a tone that can be used to test the speakers of a computer. speaker-test by default will test the default device. If you want to test another sound device you will have first to get a list of all of the sound cards in your system and the devices associated with those cards. Notice that there might be for example, one device for analog sound, one for digital sound and one for HDMI sound. To get the list of available cards and devices you can run aplay -L. $ aplay -L null Discard all samples (playback) or generate zero samples (capture) default:CARD=ICH5 Intel ICH5, Intel ICH5 Default Audio Device front:CARD=ICH5,DEV=0 Intel ICH5, Intel ICH5 Front speakers surround40:CARD=ICH5,DEV=0 Intel ICH5, Intel ICH5 4.0 Surround output to Front and Rear speakers (...) in the above example, there are four devices listed: null, default, front and surround40. So, if you want to test the last device you can run speaker-test -Dsurround40:ICH5 -c 6. The -c option will indicate that the six audio channels in the device have to be tested. OPTIONS
-c | --channels NUM NUM channels in stream -D | --device NAME PCM device name NAME -f | --frequency FREQ sine wave of FREQ Hz --help Print usage help -b | --buffer TIME Use buffer size of TIME microseconds. When 0 is given, use the maximal buffer size. The default value is 0. -p | --period TIME Use period size of TIME microseconds. When 0 is given, the periods given by -P option is used. The default value is 0. -P | --nperiods PERIODS Use number of periods. The default value is 4. -r | --rate RATE stream of RATE Hz -t | --test pink|sine|wav -t pink means use pink noise (default). Pink noise is perceptually uniform noise -- that is, it sounds like every frequency at once. If you can hear any tone it may indi- cate resonances in your speaker system or room. -t sine means to use sine wave. -t wav means to play WAV files, either pre-defined files or given via -w option. You can pass the number from 1 to 3 as a backward compatibility. -l | --nloops COUNT Specifies the number of loops. Zero means to run infinitely. When -s option below with a valid channel is given, speaker-test will perform always a single-shot without looping. -s | --speaker CHANNEL Do a single-shot speaker test for the given channel. The channel number starts from 1. The channel number corresponds to left, right, rear-left, rear-right, center, LFE, side-left, side-right, and so on. For example, when 1 is passed, it tests the left channel only once rather than both channels with looping. -w | --wavfile Use the given WAV file for the playback instead of pre-defined WAV files. -W | --wavdir Specify the directory containing WAV files for playback. The default path is /usr/share/sounds/alsa. USAGE EXAMPLES
Produce stereo sound from one stereo jack: speaker-test -Dplug:front -c2 Produce 4 speaker sound from two stereo jacks: speaker-test -Dplug:surround40 -c4 Produce 5.1 speaker sound from three stereo jacks: speaker-test -Dplug:surround51 -c6 To send a nice low 75Hz tone to the Woofer and then exit without touching any other speakers: speaker-test -Dplug:surround51 -c6 -s1 -f75 To do a 2-speaker test using the spdif (coax or optical) output: speaker-test -Dplug:spdif -c2 SEE ALSO
