Yes (AXC-SM12)

Universal cable for Axtel wired headsets.
Maxwell 10 and Maxwell 3 / B tests were
performed using this cable with following
switch positions:
1.Standard

7.Microphone boost

Jack 2,5 mm cable for Axtel headsets.
SL750H PRO, S650H PRO and R650H PRO
tests were performed using this cable.

Following limitations are known:
- Call Waiting is signaled on the PRO BT duo headset, but cannot be answered/rejected with its button. However, it can be accepted using the DECT handset, from where you can also toggle between calls or combine calls into a conference call*
- Call initiation via the headset button is not possible. This applies when you enter a number from the DECT handset's keypad and want to dial it, or when you want to call back from missed/received/dialed lists. In such cases, the call must be started with the off-hook ("green handset") key on the DECT handset. If the headset is connected and active, then the call is started using it by default.

^{*if used DECT system supports it}

Dual mode:
- The headset allows pairing with two phones (e.g., a DECT handset and a smartphone). The above functionality was tested with the listed DECT handsets and the Gigaset GX4 smartphone. In such a combination, the possible features are:
- accepting/rejecting a call via the headset button
- signaling an incoming call on the second device while talking on the first device; this call can also be accepted/rejected directly via the headset button. If a call is accepted, the audio track is connected to the second call, while the first is muted. When the second call is disconnected, the audio path of the first call is automatically restored.
