[cisco-voip] Fw: Fax with ATA on CME

[Jawad A Hai]

Hello All,

Actually I don't get the FAX tone from the FAX Machine (Panasonic DP-180).
When I try to call on the same, after a ring I only get to hear blank...

Any ideas

Hello All,
I am facing a strange problem with FAX on ATA. I have CME on 2851.
I have SIP inbound from Telco. 
My dial peer for incoming calls from Telco.

dial-peer voice 444 voip
 description ***FAX***
 destination-pattern 2871023
 modem passthrough nse codec g711alaw
 session target ipv4:192.168.12.22                   (ATA IP)
 fax rate disable
 no vad

voice service voip 
 allow-connections h323 to h323
 allow-connections h323 to sip
 allow-connections sip to h323
 allow-connections sip to sip
 fax protocol t38 ls-redundancy 0 hs-redundancy 0 fallback none
 modem passthrough nse codec g711alaw

My ATA is h.323 end point.
Attached is the screenshot of ATA
Connect Mode 0x90000404
Audio Mode is 0x00000015

The Problem is I can send FAX from ATA without a problem. But receiving FAX or Phone call on ATA is the problem.
I saw the call history it shows as call is coming from g.729. But I don't have this codec any where. I feel due to this reason 
am not able to receive. For outgoing from ATA I see both call legs on g.711alaw.
