SRST V4.0 fax passthrough support on ATA186

Hi,

I have one router 2851 ios 12.4(11)T and working with SRST v4.0 connected to PSTN. I have one ata 186 (SCCP version 3.02.01(050429A)but i can?t receive faxes from PSTN . In config guide say

"For ATAs that are registered to a Cisco Unified SRST system to participate in FAX calls, they must have their ConnectMode parameter set to use the "standard payload type 0/8" as the RTP payload type in FAX passthrough mode. For ATAs used with Cisco Unified SRST 4.0 and higher systems, this is done by setting bit 2 of the ConnectMode parameter to 1 on the ATA."

Is that 0X90000404????? or what value?

audio mode i have 0X00350035

In gateway what i need to config fax passtrough???

Best Regards,

MC

Re: SRST V4.0 fax passthrough support on ATA186

Hi,

I managed to get our fax working with settings:

ConnectMode: 0x90000400

AudioMode: 0x00150015

I don't really know the settings in the gateway because I don't configured it myself.

Best Regards

Daniel Larsson
