Try to change something in zaptel/tonezone.c around these lines
                /* Bring it down -8 dbm */
                gain = pow(10.0, (LEVEL - 3.14) / 20.0) * 65536.0 / 2.0;

                td->fac1 = 2.0 * cos(2.0 * M_PI * (freq1 / 8000.0)) *
32768.0;
                td->init_v2_1 = sin(-4.0 * M_PI * (freq1 / 8000.0)) *
gain;
                td->init_v3_1 = sin(-2.0 * M_PI * (freq1 / 8000.0)) *
gain;

                td->fac2 = 2.0 * cos(2.0 * M_PI * (freq2 / 8000.0)) *
32768.0;
                td->init_v2_2 = sin(-4.0 * M_PI * (freq2 / 8000.0)) *
gain;
                td->init_v3_2 = sin(-2.0 * M_PI * (freq2 / 8000.0)) *
gain;

However, when voice conversations and voicemail recordings are at good levels then the dial tones, busy tones, etc are way too loud.  This is especially true for the chirp for call-waiting which is excruciating for someone who is having a conversation.
