Debugging the Cisco ATA 186/188 Fax Services
Example 6-7
---------- FAX Summary 1 ----------
[ 37]<2.53=>3.200> Codec G711
[ 39]<3.200=>2.53> Codec G711
[ 1820]<2.53=>3.200> NSE PT
[ 1966]<2.53=>3.200> NSE PT
Analysis
<2.53> is the originating gateway and <3.200> is the terminating Cisco ATA.
•
The Cisco ATA and the <2.53> gateway begin with G.711 codec.
•
The <2.53> gateway sends Cisco fax relay event packets.
•
Possible Cause for Failure
Cisco fax relay option is not disabled on the gateway.
•
Example 6-8
---------- FAX Summary 1 ----------
[ 2]<2.53=>3.200> Codec G723
[ 4]<3.200=>2.53> Codec G723
[ 106]<3.200=>2.53> Codec G711u/D
[ 107]<3.200=>2.53> NSE PT 100, EVT 192: Up-Speed, CED tone Detected
[ 1436]<3.200=>2.53> NSE PT 100, EVT 192: Up-Speed, CED tone Detected
Analysis
<2.53> is the originating gateway, and <3.200> is the terminating Cisco ATA.
•
The Cisco ATA upspeeds to G.711µ-law and sends G.711 upspeed NSE signaling packets.
•
The <2.53> gateway does not respond to the NSE signaling packets.
•
Possible Causes for Failure
Fax/modem pass-through option is not enabled on the gateway.
•
Fax/modem pass-through NSE payload type are configured differently on the Cisco ATA and the
•
gateway.

Analysis
<2.53> is the originating gateway, and <3.200> is the terminating Cisco ATA.
•
• The Cisco ATA upspeeds to G.711µ-law and sends G.711 upspeed NSE signaling packets.
• The <2.53> gateway upspeeds to G.711µ-law and then sends Cisco fax relay event packets.
