This turned out to be a setting in Rightfax. Now working again! Many thanks to Troy Putnam for emailing me the fix outlined below:
In RightFax: Log into the Brooktrout Configuration tool --> IP Call Control Modules --> SIP --> T.38 Parameters, and change the Media Renegotiate Delay Outbound, msec: from -1 top 500. -----Original Message----- From: Charles Goldsmith [mailto:[email protected]] Sent: Thursday, April 30, 2015 5:36 PM To: Haas, Neal Cc: Countryman, Edward; Cisco VOIP Subject: Re: [cisco-voip] CUCM 10.5 and OpenText 10.6 There are no timers in the SIP trunk, but the SIP Profile has several. Please let us know which timer you find that resolves this? I have a customer that will be going to 10.5 soon and are using RightFax. Also, RightFax has some good documentation and support, they may have this already covered.
