i have a number of sip clients that currently make and receive calls, however when trying to sent a text massage (using sip protocol) between each other i have to establish a voice call first to create a channel that i could use to send a text massage.
The problem with SendText() application is that
"SIP Supports text messaging during a call, but not outside of a call".
my sip client is Bria
This is AMI action
Channel: SIP/1004-00000011 //as you can see i need to have an existing channel
Message: “Hi i am testing sending text using sip protocol”
exten => 1004, 1, Answer()
exten => 1004, n, SendText(hello world)
exten => 1004, n, HangUp()
I really need your help
