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. Example 7-9 Fax Pass-through Mode Failure ---------- FAX Summary 1 ---------[ 37]3.200> Codec G723 [ 39]2.53> Codec G723 [ 143]2.53> Codec G711u/D [ 144]2.53> NSE PT 100, EVT 192: Up-Speed, CED tone Detected [ 1602]2.53> NSE PT 100, EVT 192: Up-Speed, CED tone Detected [ 1604]3.200> Codec G711u/D [ 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 upspeeds to G.711µ-law and sends G.711 upspeed NSE signaling packets. • The gateway upspeeds to G.711µ-law and then sends Cisco fax relay event packets. Possible Cause for Failure • Cisco fax relay option is not disabled on the gateway. Example 7-10 Fax Pass-through Mode Failure ---------- FAX Summary 1 ---------[ 33]2.53> Codec G729 [ 39]3.200> Codec G729 [ 562]3.200> NTE PT 101, EVT [ 563]3.200> NTE PT 101, EVT [ 565]3.200> NTE PT 101, EVT [ 566]3.200> Codec G711u/D [ 568]3.200> NTE PT 101, EVT [ 580]2.53> Codec G711u/D 34: Modem Mode, ANSam tone Detected (RFC2833) 34: Modem Mode, ANSam tone Detected (RFC2833) 34: Modem Mode, ANSam tone Detected (RFC2833) 34: Modem Mode, ANSam tone Detected (RFC2833) Analysis • is the originating Cisco ATA, and is the terminating gateway. • Both sides initially use G.729.
