ATA 186 behaving unreliably with Toshiba DP120F fax machines

[PETER NEGUS]

I have problems with Toshiba DP120 F fax machines receiving faxes via an ATA 186 and an H323 gateway. The gateway is configured with "Modem passthrough nse g711ulaw" and the ATA has the audiomode 0x00150015 and connectmode parameter 0x90000400. Has anyone else had problems with these devices in fax passthrough mode and solved the problem? The strange thing is that some of them seem to work fine and others do not - is there a known software issue with the device?

[PETER NEGUS]

I should add that the fax machines connect fine, but the problem ones fall over and abort the call after receiving one or two pages.

[bretjaquish]

Perhaps the settings in the fax machines themselves are different. It might be prudent to reset all the fax machines to a default configuration, or compare/contrast the differences between the ones that work and do not work.

guys,

same problem i am also facing .. i have ATA 186 configured with CCME 7.1 .. some time fax working fine and some time not receiving neither sending ... ATAs are integrated with Toshiba and Sharp fax machine ... on both of them i am facing same problem !!!!

can any one tell how to troubleshoot it ??

Hi,

also had fax problems on ATAs before. Try setting the send/recv rate on the fax to 9600 baud, and turn ECM off. This does the trick most of the time.

hi ,

i tried to set 9600 baud on fax machine but no luck ... any other reason !!!!

Check for problems on the switchport interface connected to the ATA. Check for errors/collisions on all interfaces in the path between the two devices. So is this on-net faxing? Faxing from one ATA to another or from the PSTN to the ATA?

[riazshams]

hi,

internal fax between ATA's are working fine .. but if some one send fax from PSTN or if i send fax to PSTN then i am facing problem .. some time fax are going some time not some time not going complete ... below is sh run of ccme ...

Please reply urgently if there is any mistake in dial-peers !!!

Regards

[riazshams]

one thing i forget to tell in above post, that i have tested out the analog line by replacing it from ATA to directly in FAx machine .. its working fine ... so it means there isnt any problem into analog line ...

i guess problem is in dial-peer of sending and receiving fax ... .

can any one tell via have alook on above config that where is the mistake ...

plz reply urgently and thanks in advance

[chadlincoln]

Try putting this under your dial-peer voice 100 voip:

modem passthrough nse codec g711ulaw

dtmf-relay rtp-nte h245-alphanumeric

fax rate disable

Please rate if this helps.

[riazshams]

Gents,

I have got resolved ATA working fine without configuring dial-peer and special commands for Fax or ATA's ...

actually i had uploaded the firmware of ATA into flash but after uploading i didnt reboot the system !!!! so yesterday i just reboot my system and all things started to work perfectly !!!!

thanks for all of guys for help and suggestion .. if some one wants tell me i can share the running config ....

Thanks

Check you E1 controller, you may also having slips, for which you need network-clock-participate and network-clock-select. The usual symptom is inability to send or recieve faxes made of many pages.
