Free calls to other PlusNet Home Phone users?

[#1]

AFAIK all SIP to SIP calls should be free, even if not Plusnet to Plusnet.
To ensure that they are, you may have to dial them as 1234567@sip.plus.net rather than as 01...etc. That ensures that they don't drop out to the PSTN network & then back again (which is where the charging kicks in).
This is where a proper SIP phone comes in, rather than an analogue phone connected to an ATA, because they will only dial numbers.

this is a home phone question not VOIP

Obviouly calling someone else on Homephone E/WE in the evening / weekend is free - but somewhere I read that even during the day calls between Homephone users is free ?

Mal, my calls to my sister are always free, whatever time of day I ring her. I'm on Evening and Weekend. Hers to me were being charged and she's on Essential (which just has free weekend calls). That, which shouldn't have happened, is the 'known problem' that's due to be fixed tomorrow.
This is all Home Phone to and from landlines, just in case you've got confused by Simon's post where he's mixed Home Phone up with Broadband Phone.

Silly me.
That's what comes of arriving at a thread via 'Unread Posts' instead of by forum title. I had VoIP on the brain at the time.
Apologies.

Thanks guys - and no hassle about VoIP - I don't bother with that as I don't make a tremendous amount  of calls and have no son's or daughters phoning appropriate partners
