ATA Config for FAX incoming and out going using H.323 or SCCP

[lburke]

Hi Guys,
Has anyone had any success in configuring an ATA 186 for either SCCP or H.323 and if so have you any helpful tips on how to do so? I am using Callmanager Express 3.2.
I have had no luck whatsoever in getting it working in H.323, i.e. I cannot even get a dial-tone in H.323 mode.
I have set the gateway IP address using the ATA's webpage, but it doesn't want to play ball.
When I used SCCP and a dial-peer voice 1 pots setup on the CME router, which shoves the call out to the e1 serial controller.
When using this setup, the ATA is configured as an ephone-dn and does register with the ccme, I get a dial tone and all seems to work until I try to send or recieve a fax. Occasionally recieving a fax works, but sending proves to be a disaster... You can hear it try to sync with the fax on the other end, but it seems to resync during the actual send, and I get a comms-error on the fax connected to the ata.

Please help, if you can!

H.323 config on ccme:
dial-peer voice 1 voip
destination-pattern 4599
modem passthrough nse codec g711ulaw
session target ipv4:192.168.22.1
incoming called-number .
dtmf-relay h245-alphanumeric
codec g711ulaw
fax rate disable


Dial-peer config for SCCP:

dial-peer voice 1 pots
description Dial 9 for PSTN
preference 7
destination-pattern 9T
incoming called-number .
fax rate disable
direct-inward-dial
port 1/0:15



Thanks and many many regards,
Liam Burke

Hi,

I'm having the same issues, although I'm able to get my ATA to work via SCCP (CCME Skinny doesn't support fax passthru, that's why the faxes won't work) I'm able to get dial-tone with the H323 by configuring a DN on the UID0 (port 1) of the ATA's GUI config page. See if this at least gets you a dial-tone, and let me know if you get it working.
