Hi,

There needs to be consistancy with the fax protocol config throughout the network

So on the vg202 you have

!
voice service voip
fax protocol pass-through g711ulaw
modem passthrough nse codec g711ulaw
! 

Thats fine - so we are going to use fax/modem passthru as the protocol.

In the ccm page you shared set the options to match

Modem Passthrough = Enable
T38 Faxelay = Disable

Save & reset

On the MGCP gateway

!
ccm-manager fax protocol cisco
mgcp fax t38 inhibit
mgcp modem passthrough voip mode nse
mgcp modem passthrough voip codec g711ulaw
!

Regards
Alex

Hi Alex,

Thank you for your help!
 

I have configured VG202:

voice service voip
 fax protocol pass-through g711ulaw
 h323
 modem passthrough nse codec g711ulaw
!

In the ccm page you shared set the options to match

Modem Passthrough = Enable

Cisco Fax Relay = Enable ?
T38 Faxelay = Disable

Save & reset

On the MGCP gateway

ccm-manager fax protocol cisco
mgcp fax t38 inhibit

Tips: Reset the Gateway on CCM if this Gateway registered with Cisco Call Manger (CCM)

mgcp modem passthrough voip mode nse
mgcp modem passthrough voip codec g711ulaw
!

I also need Reset the voice gateway on CCM if this gateway registered with CCM?
