[asterisk-users] Asterisk Double Invite

[Steve Howes]

Hi,

This message was also sent to the list on the 23rd. Perhaps your mail  
client is suffering from a 'double post' fault. Maybe it is similar to  
Asterisk's double invite affliction. In fact, looking back at your  
post history this is not uncommon and you appear to post the same  
questions again and again if you do not get the answer you desire. Ask  
once, if you don't get a reply its either a stupid question, or nobody  
knows. Either way its time to do some research of your own.
