[OpenSIPS-Users] Dialog Cancel Error

[Seth Schultz]

Hello,

I am seeing the following error message 
"ERROR:dialog:push_reply_in_dialog: missing TAG param in TO hdr :-/".  
It appears to occur directly after a CANCEL request (between a 100 
Trying and 180/183 reply).  Think of it as someone dialing a number and 
then hanging up before the call has a chance to really start.  Is there 
a way to suppress this error if the transaction has been cancelled?

Please review the SIP trace below as an example of where this error 
occurred.

Thanks,
Seth
