Call Diversion - hit and miss on DV?

Tim123 — Tue, 09 Jun 2026 23:44:26 GMT

Anyone else find that Call Diversion is hit or miss on Digital Voice? I have three mobile phone numbers (don't ask), all using the Vodafone network. Only one of the numbers works for diverts, the other two make my line appear engaged to the caller. Never had this problem on PSTN!

Also annoying that calling *#21# to check which number is set up for diverts doesn't work on DV (just silence), I have to cancel the divert and then re-add it to be sure. Calling *#61# or *#67# does work, but only to say that the respective divert is in operation (they don't tell me the number as PSTN did).

Hi @Tim123

Thanks for reaching out about this.

It's sounds like you're familiar with how call diverts work, but if you wanted to check they were set up correctly, you can see our All about Call Diversion for Digital Voice help page.

If you are still having trouble with this, our technical team would be happy to run through some checks with you to see if they can get to the bottom of this.

I worked out what the problem was. I had Call Barring set up to bar calls to mobile phones, using option 6. (Incidentally, that option was not available on PSTN, probably because few people had mobiles when the feature was launched many years ago, and is still not mentioned in the online instructions for Call Barring.)
Removing the mobile phone bar allows calls to be diverted to the two mobile numbers again.
Of course, this doesn't explain why only two of my mobile numbers were affected and not the third! Reapplying the bar confirms that I can call the 'third' mobile number from my landline but not the other two.
So BT Call Barring interprets one of my mobile phone numbers as a landline number. Very odd.
