Possible Causes for Failure • The Cisco ATA is not configured with fax mode or fax pass-through mode. • If the Cisco ATA is the gateway for a fax sender, the remote gateway is not configured with fax pass-through mode. Example 7-7 Fax Mode Failure ---------- FAX Summary 1 ---------[ 37]3.200> Codec G711 [ 39]2.53> Codec G711 [ 1820]3.200> NSE PT 96, Cisco Fax Relay [ 1966]3.200> NSE PT 96, Cisco Fax Relay Analysis • is the originating gateway and is the terminating Cisco ATA. • The Cisco ATA and the gateway begin with G.711 codec. • The gateway sends Cisco fax relay event packets. Possible Cause for Failure • Cisco fax relay option is not disabled on the gateway. Example 7-8 Fax Pass-through Mode Failure ---------- FAX Summary 1 ---------[ 2]3.200> Codec G723 [ 4]2.53> Codec G723 [ 106]2.53> Codec G711u/D [ 107]2.53> NSE PT 100, EVT 192: Up-Speed, CED tone Detected [ 1436]2.53> NSE PT 100, EVT 192: Up-Speed, CED tone Detected Analysis • is the originating gateway, and is the terminating Cisco ATA. • The Cisco ATA upspeeds to G.711µ-law and sends G.711 upspeed NSE signaling packets. • The 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. 7-18 Cisco ATA 186 and Cisco ATA 188 Analog Telephone Adaptor Administrator's Guide (SIP) OL-3410-01
