[cisco-voip] Fax topology with ITSP/CUBE and VG310

[Prashanthi Velpula (prvelpul)]

Hi Daniel,



As VG310 supports T.38 fax relay, and modem pass-through and your call flow says:

- VG310 as SCCP, then you will be limited to use T.38 fax relay methods. As Protocol-based switchover is not supported with SCCP.

- And provider not supporting any fax relay methods, then you will need to do the below:



Call Flow:

ITSP -- > SIP -- > CUBE -- > SIP -- > CUCM -- > SCCP -- > VG310 -- > FXS -- > FAX_Machine



On the VG310:

fax protocol t38 nse ls-redundancy 0 hs-redundancy 0 fallback pass-through <g711ulaw or g711alaw>



On the CUBE:

fax protocol pass-through {g711ulaw | g711alaw}



Hope the above helps.

Regards
