Issue is some of my sites have poor line quality. Sometimes i can replace the lines and it fixes the issues. Is there any commands on IOS i can use to adapt for line quality issues? I use g711 always for faxing.
Specifies the fax protocol for all VoIP dial peers. Keywords and arguments are as follows:
•nse—(Optional) Use of Cisco named service events (NSEs) for fax signaling.
•force—(Optional) Required use of NSEs for fax signaling, which permits interworking of H.323 or SIP gateways with MGCP gateways for T.38 fax relay.
•ls-redundancy—(Optional) Number of redundant T.38 fax packets to be sent for the low-speed V.21-based T.30 fax machine protocol. Range varies by platform from 0 (no redundancy) to 5 or 7. For details, see CLI help. Default: 0.
•hs-redundancy—(Optional) Number of redundant T.38 fax packets to be sent for high-speed V.17, V.27, and V.29 T.4 or T.6 fax machine image data. The value range varies by platform from 0 (no redundancy) to 2 or 3. For details, see CLI help. Default: 0.
Note Setting the hs-redundancy parameter greater than 0 causes a significant increase in the network bandwidth consumed by the fax call.
Exits voice-service configuration mode.
