Home office with fax
Preconditions are those used in section “Home office in an enterprise network” on page 591: low bandwidth
and high jitter. In this example, bandwidth is 256 kbps, what enables us to use the G.729 codec. But since the
fax protocol must also be supported, the configuration is extended:
1 node>enable
2 node#configure
3 node(cfg)#profile voip g729_FaxRelay
4 node(pf-voip)[g729_Fa~]#no codec g711aLaw64k
5 node(pf-voip)[g729_Fa~]#no codec g711uLaw64k
6 node(pf-voip)[g729_Fa~]#codec g729 tx-length 20 rx-length 20 silence-suppression
