AT&T Verizon to block text messaging
by orenyny＠gmail.com March 7, 2021

March 7, 2021

Hello, Does anyone have some deep knowledge about AT&T and Verizon's move to create their own walled gardens and prevent messages from the outside world from coming in, unless they approve each and every phone number (and you obviously pay for that approval)? Next thing they will block emails from other networks, or maybe all IP traffic. Thanks, Oren

Grandstream call forwarding and local calling features
by caalvarez＠gmail.com March 3, 2021

March 3, 2021

We primarily use their phones in a hosted service. A recent firmware change has made it so that call forwarding on the phone ONLY works if you have "enable local calling features" turned on. We always had it off, because we use *number for a lot of other special purposes. For example, *extension is to transfer calls directly to VM. *CO is each customer's conference bridge. Etc. If you enable local features, the phone traps anything that pattern matches their built in, partially undocumented codes. So a customer with extensions like 30x cannot dial *309 to send the call to VM. Anyone have ideas on this?

Wholesale MMS Group Messaging and Applications
by colton.conor＠gmail.com March 1, 2021

Which wholesale voip carriers successfully support Group Messaging? I know bandwidth.com does as they have a whole section about it on their webpage below. Does Intelliquient, Level3/ CenturyLink, Flowroute, Telnyx, Twilio, or other providers? Note, this is different than just regular SMS or MMS support. I think most all carriers support SMS, some support MMS, and few support group MMS. A better question is what softswitch, apps, or platforms support the MM4 or API of said wholesale carriers assuming they support Group messaging? For example, I think bandwidth supports the API/MM4 protocol, but they do not provide the end customer facing applications. They want you to hire a programmer to do this. Broadsoft and Metaswitch don't support MMS to my knowledge as they are built on XMPP for chatting protocols. They support SMS, but not MMS nor group MMS to my knowledge. Netsapiens does not either, I believe. 2600hz only does SMS. Who else out there has native MMS support? Group Messaging is characterized by an SMS conversation among 3 or more recipients at the same time. This is a many-to-many exchange of messages. Group messaging is typically sent as MMS messages. Bandwidth offers a ready-to-use API for Group Messaging besides the ability to send group messages over its MM4 platform. https://www.bandwidth.com/glossary/group-messaging/
