I sent off a costumer support request to Jabra and got the following back from them. I tried the following procedure several times and I am now able to get the last number called function working but the hold and three way are still non functional.
I have not herd about the 250V and 7250 being non compatible though I would find that a surprise seeing as I purchased both items together from Verizon.
If we are all having problems with the 250V functions lets all give Karl a call at Jabra technical support, the number is listed below.
Thank you for contacting JABRA North America!
You may need to hard reset your phone and start the pairing process again. I've listed some steps below for you to try. Please make sure headset and cell phone are fully charged before starting this process.
Hard Reset:
1. Delete "JABRA BT250/BT200" from your phone.
2. Turn cell phone off completely, remove battery and sim card. 3. Put headset in cradle, connect it to the outlet and let it charge for 10 seconds.
4. Put sim card and battery back in then turn cell phone on but do not touch any settings.
5. Remove headset from cradle.
6. Turn off the headset.
6. Press phone symbol and volume up button until you receive steady blue light.
7. Put headset aside and start the pairing process on your cell phone. The pass code is (0000)
Please feel free to contact us if you have any further questions.
