AS5400XM not send MCF

Unanswered Question
Mar 19th, 2009

Hi all!

There was a problem with a fax assurance of receipt. According to the standard t.38 after fax reception message MCF should go, however Cisco AS5400xm it does not send. Because of it softswitch MERA does not confirm fax reception.

What problem may be?

That doesn't appear to be a situation that warrants a MCF - that looks like a failed fax negotiation before the pages are sent.
