Re: [PLUG] VOIP texting - was Help with Postfix SASL auth to smarthost on RedHat distro

OK, so WhatsApp seems to work with a number other than your cell number, but this is still only useful for those people

running the WhatsApp. I'll give at try for a while looks like it has a good amount of features. I notice that most of my

WhatsApp connections have not been online for days - so maybe they just tried it, but don't have the app running on startup ?

I'm looking for a method for one messaging service that I can reach on the desktop or mobile, just like I have one VOIP number

that I can answer from office or mobile. Is their a good reliable android app for XMPP/jabber , as I know Pidgin works great on the Desktop.

I found one alternative is to use SMS to voip ( via my VOIP provider's s.ms service ) then setting up the inbound SMS

message to be sent to my email, which then shows up on the phone.

I make the s.ms source a priority contact, so my phone pings on receipt and shows the message on the status screen. So

in effect it's working much like an SMS message ( and I can get them from any of my VOIP numbers )

I can reply to the SMS email, and a reverse SMS is sent back to the originator.

I've been using WhatsApp with a Google Voice number (so it's not my real number). It works well and is widely supported.

I have a question. What do people use these days for texting ?

SMS was popular on mobile phones, but doesn't have support by most VOIP carriers.
Many VOIP carriers have inbound SMS, but the clients are often XMPP , not the native SMS client.

Even FreePBX 14 now has an embedded XMPP server, but that's not useful unless you
have a whole company on your PBX. Pidgin on Linux talked to FreePBX XMPP easily.
Or maybe people register with a whole bunch of XMPP services ?

I would like to not publish my cell number since I route my incoming VOIP trunks to it, so
the cell's SMS capability doesn't hide the cell number for me.

I've also notices that WhatsApp is popular, and I have an unexpected number of
business and family with accounts. That service can be used on the phone with
any inbound number that receives texts so that may work for me.

What are people using these days for texting? So many choices.
