Thanks for reminding me to close down those gmail security exceptions, as I'm running my
voicemail messages through my main SMTP server now, over TLS/SASL.
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.
Lee
