Faxes on an Avaya CM 5.0 and G450 gateways are disconnecting

[hunterrob]

I have an Avaya on CM 5.0 with G450 Gateways, when a large fax comes in, over 2 pages the call disconnects before the full document is recieved. They are on PRI DS1's

post the IP-codec page for the Network Region that the Fax extensions are in. You probably need a tweek to the ip-codec set.

AvayaTier3, hunterrob has a G450, he would need to do this:

telnet or SSH into the G450's PMI, then:

"set sync interface primary v4" (if your DS1 in in slot 4 for example)
"set sync source primary"
"show sync timing" (to see if you are now syncing off the PRI/T1)

don't forget to do a "copy running-config startup-config" so the changes happen on the next reboot/powerdown

Check page 2 of the codec set. Are faxes and modems set to pass through or relay? Should be set to pass through.

PRI/T1 synchronization, and the IP-Codec set FAX settings are the 2 things to look at, yes. This is why they have both been mentioned already

Thanks, did that will monitor to see if it helps

Thanks Mitch. You can tell that these new gateways are not in my area of expertise and I don't usually respond for things I know nothing about.
