Hi Frank, SPA122 only

Hi Frank,

 

SPA122 only supports the following fax protocols:

 

Fax pass-through using G.711

T.38 fax relay

 

I am not sure what you have configured on your Gateway, please make sure that you add the following commands on the gateway.

 

mgcp modem passthrough voip mode nse

mgcp modem passthrough voip codec g711ulaw

Hi Frank, These FXO ports

Hi Frank,

 

These FXO ports should be controlled by CUCM using MGCP or you are using these gateway using any other protocol(SIP/H323).

 

If we are using MGCP, then please check the route patten through which you are sending the call out to the Gateway.

Hi Amit,Route pattern

Hi Amit,

Route pattern configured with specific number (021248454) that i want to dial via FXO port and pointed to FXO port as gateway.

when i dial to that number it will generate busy tone call route to the GW but not going through FXO port

 

Thanks,
