We are having issues with receive fax's over our SIP trunk. Voice calls ok no issues at all. the fax's are not using T38. The problem we have is that with some fax's we only receive 1/2 a page, others nothing at all, sender and receive get comm error and some that are received ok. We have found that some fax machines work better than others, but even the best fax we have so far fails after about 3 pages of receive with COMM error. Most times if you send a test fax with just "test fax" on paper its received ok, however if you send a fax with images etc only 1/2 page is received. Most people seem to say this is common issue. Is there some standard settings that should be used ? Have tried with modem passthrough and without, tried ctraete in/out dial pear with various settings but no luck so far. Any idea what we should set and what should not be set to get this to work.
- Check, double check & tripple check your QoS settings across the board. Faxes are very sentitive to packet delay & loss. Look at the CUCM CMR records to see what the call stats are like of these failed fax calls.

answer. Be sure to read the whole thing or e...
