I assume the DECT phone is the one connected to SPA while "my phone" is located elsewhere.
1) I have no experience with SPA2102. May be you hit a firmware bug, may be the behavior is intentionally different. I have no SPA2102 in my test lab, so I can't test it. With CPC and permanent off-hook you will get dial tone periodically on all ATAs I know.
2) There's no signal like CPC defined for calling side. CPC may or may not be supported by phone as non-standard feature, unfortunately, it's unimportant as SPA doesn't use CPC for calling side phone. As far as I know, of course ...
There's not so much we can do for your mother. Either you need a DECT phone that can detect busy tone and hang up automatically.
You may use a direct ATA<->DECT convertor (e.g. with no intermediate POTS analog line), like SPA232D ATA with SPA302 handset. With limits of POTS line the ATA can force handset to go off-hook. I can't claim for sure you will be satisfied - just attempt to advise possible solution.

Hi Gerhard, I found this doc: CadScript—A mini-script that specifies the cadence parameters of a signal. Up to 127 characters. Syntax: S1[;S2], where: Si=Di(oni,1/offi,1[,oni,2/ offi,2[,oni,3/offi,3[,oni,4/offi,4[,oni,5/offi,5[,oni,6/offi,6]]]]]) and is known as a section, oni,j and offi,j are the on/off duration in seconds of a segment and i = 1 or 2, and j = 1 to 6. Di is the total duration of the section in seconds. All durations can have up to three decimal places to provide 1 ms resolution. The wildcard character “*” stands for infinite duration. The segments within a section are played in order and repeated until the total duration is played. Example 1: 60(2/4) Number of Cadence Sections = 1 Cadence Section 1: Section Length = 60 s Number of Segments = 1 Segment 1: On=2s, Off=4s Total Ring Length = 60s Example 2—Distinctive ring (short,short,short,long): 60(.2/.2,.2/.2,.2/.2,1/4) Number of Cadence Sections = 1 Cadence Section 1: Section Length = 60s Number of Segments = 4 Segment 1: On=0.2s, Off=0.2s Segment 2: On=0.2s, Off=0.2s Segment 3: On=0.2s, Off=0.2s Segment 4: On=1.0s, Off=4.0s Total Ring Length = 60s FreqScript—A mini-script that specifics the frequency and level parameters of a tone. Up to 127 characters. Syntax: F1@L1[,F2@L2[,F3@L3[,F4@L4[,F5@L5[,F6@L6]]]]], where F1–F6 are frequency in Hz (unsigned integers only) and L1–L6 are corresponding levels in dBm (with up to 1 decimal places). White spaces before and after the comma are allowed (but not recommended). Example 1—Call Waiting Tone: 440@-10 Number of Frequencies = 1 Frequency 2 = 440 Hz at –10 dBm Example 2—Dial Tone: 350@-19,440@-19 Number of Frequencies = 2 Frequency 1 = 350 Hz at –19 dBm Frequency 2 = 440 Hz at –19 dBm ToneScript—A mini-script that specifies the frequency, level and cadence parameters of a call progress tone. May contain up to 127 characters. Syntax: FreqScript;Z1[;Z2]. The section Z1 is similar to the S1 section in a CadScript except that each on/off segment is followed by a frequency components parameter: Z1 = D1(oni,1/offi,1/fi,1[,oni,2/offi,2/fi,2 [,oni,3/offi,3/fi,3 [,oni,4/offi,4/fi,4 [,oni,5/offi,5/fi,5 [,oni,6/offi,6/fi,6]]]]]), where fi,j = n1[+n2]+n3[+n4[+n5[+n6]]]]] and 1 < nk < 6 indicates which of the frequency components given in the FreqScript are used in that segment; if more than one frequency component is used in a segment, the components are summed together. Example 1—Dial tone: 350@-19,440@-19;10(*/0/1+2) Number of Frequencies = 2 Frequency 1 = 350 Hz at –19 dBm Frequency 2 = 440 Hz at –19 dBm Number of Cadence Sections = 1 Cadence Section 1: Section Length = 10 s Number of Segments = 1 Segment 1: On=forever, with Frequencies 1 and 2 Total Tone Length = 10s Example 2—Stutter tone: 350@-19,440@-19;2(.1/.1/1+2);10(*/0/1+2) Number of Frequencies = 2 Frequency 1 = 350 Hz at –19 dBm Frequency 2 = 440 Hz at –19 dBm Number of Cadence Sections = 2 Cadence Section 1: Section Length = 2s Number of Segments = 1 Segment 1: On=0.1s, Off=0.1s with Frequencies 1 and 2 Cadence Section 2: Section Length = 10s Number of Segments = 1 Segment 1: On=forever, with Frequencies 1 and 2 Total Tone Length = 12s Example 3—SIT tone: 985@-16,1428@-16,1777@-16;20(.380/0/1,.380/0/2,.380/0/ 3,0/4/0) Number of Frequencies = 3 Frequency 1 = 985 Hz at –16 dBm Frequency 2 = 1428 Hz at –16 dBm Frequency 3 = 1777 Hz at –16 dBm Number of Cadence Sections = 1 Cadence Section 1: Section Length = 20s Number of Segments = 4 Segment 1: On=0.38s, Off=0s, with Frequency 1 Segment 2: On=0.38s, Off=0s, with Frequency 2 Segment 3: On=0.38s, Off=0s, with Frequency 3 Segment 4: On=0s, Off=4s, with no frequency components Total Tone Length = 20s Regards.
