1. Sending IM messages from SIP (SIMPLE capable) phones:

• While using SIMPLE capable SIP phone you may send IM messages to Google Talk or Jabber users by adding your buddy to your contact list using a simple rule below, then chat to it like it is an ordinary SIP contact. Rule:
• Substitute at-sign (@) with a string _at_ in your buddy's address,
• Append a string @gtalk.gtalk2voip.com to the end of the resulting string, so it will finally look like:

  @gtalk.gtalk2voip.com

  Example:

  If you want to IM chat with, say, , you should add a SIP contact like:
  
  or
  sip:
  

• To send IM chat messages from SIP phone to MSN/Live Messenger users, use the following rule:
• Again, substitute at-sign (@) with a string _at_ in your buddy's address,
• Append a string @msn.gtalk2voip.com to the end of the resulting string, so it will finally look like:

  @msn.gtalk2voip.com

  Example:

  If you want to IM chat with, say, , you should add a SIP contact like:
  
  or
  sip:
  

When you chat with contacts like that, all incoming messages from your buddy will come to same window, so it will look completely transparent, like you are chatting with someone using SIP phone on his/her side.

NOTE: When sending a first message to Jabber/Google Talk user, he/she will be sent an invitation from you. which he/she must accept. If not, your massages will not pass to your buddy. That's how Jabber network works!
