[SIPForum-discussion] FAX Issue in VoIP

[shawn.degraw at comcast.net]

Are you sure the dialog is getting setup properly. If the ACK to the 200ok is not making it to the far end then the 200ok will be retransmitted until the call is torn down. This can provide a temporary media path but will not stay up for multiple fax pages.
