I have a ONLINE callshop that work with IP Phones.
I'm use Asterisk.
Now I need send to IP Phones the amount call in realtime to show on Phone LCD.
I learn about this feature and fond this information:
To Phone show message on LCD, is necessary send a SIP INFO with xml data.
INFO sip:carlos @ [login to view URL] SIP/2.0
Via: SIP/2.0/UDP [login to view URL];rport;branch=z9hG4bKppggmt5mg1avj
From: <sip:01152588200 @ [login to view URL]>;tag=0tpgSjXtr3ctD
To: <sip:carlos @ [login to view URL]>;tag=as00a203e3
Call-ID: 3dccd3dc4a295a7c5391c95377a45a0d @ [login to view URL]
CSeq: 96649882 INFO
Contact: <sip:011525882XX @ [login to view URL];transport=udp>
Allow: INVITE, ACK, BYE, CANCEL, OPTIONS, MESSAGE, INFO, UPDATE, REGISTER, REFER, NOTIFY, PUBLISH, SUBSCRIBE
Supported: timer, precondition, path, replaces
<?xml version="1.0" encoding="UTF-8"?>
I get it from a system that work perfect. Each INFO received, show the currency-amount variable on LCD.
I need to it. can be in Asterisk or FreeSwitch.
If you not expert in it, please not send your proposals.
I ONLY HIRE YOU IF YOU SHOW IN MY PHONE Grandstream A MESSAGE. You send me a SIP account, I register on my phone. If I receive any custom message on LCD I hire you.
