Description:	T.140 is working perfectly between two Real-Time Text enabled phones. When I turn on Red, both phones start getting text instantly, not initiated by either phone. On one phone, the character a along with anoter is repeated constantly. On the other phone, the character j along with another is repeated constantly. If I try sending text between the phones, the T.140 makes it through, but the a and j characters still come across as well.

Colp (jcolp) 2021-07-28 09:52:42.703-0500 Just a heads-up that the T.140 functionality is community supported, if this issue is accepted then there is no time frame on when or even if it would get looked into. By: Sean Bright (seanbright) 2021-07-30 15:30:46.815-0500 [~clay.dirkschneider], can you attach a packet capture (.pcap) showing the conversation? Additionally, what phone are you using? By: Sean Bright (seanbright) 2021-08-02 09:27:04.321-0500 What phone are you using? The User Agent is {{HIN-C12/1.1.209 (belle-sip/1.6.1)}} but Google isn't helping me find it. By: Clayton (clay.dirkschneider) 2021-08-02 09:39:01.085-0500 We are using rebranded IP Video phones with android. There is a custom built app on the phone that handles SIP and RTT. By: Sean Bright (seanbright) 2021-08-02 09:45:57.043-0500 Got it. Thanks. By: Sean Bright (seanbright) 2021-08-02 15:07:37.920-0500 [~clay.dirkschneider], any chance you could take a video of what you are seeing? Without a test device it is going to be difficult for us to reproduce. By: Clayton (clay.dirkschneider) 2021-08-02 16:06:54.163-0500 It is attached. By: Sean Bright (seanbright) 2021-08-02 16:53:34.316-0500 Interesting. Thank you.
