DTMF feature in SIP Trunks

Hi,

We configured a SIP trunk connected to a Provider, calls were fine however if there is a need to use the DTMF feature the client cant dial the extension they want to call. Is there a possible way we can use that feature in a SIP Trunk?

Thanks,
Jonnel

find out whether the the provider using inband or outband dtmf. I also facing the same problem when i tried to connect to 3rd party IVR, it seem the OXE only support the outband dtmf

Jonnel,

Most of SIP is using G711 codec, but some like Verizon are using G729 in the USA.
This will make a difference in the DTMF (inband / outband).
Can you figure it out and let us know ?

Thanks

Hi Frank,

Thanks for the advice, I made some adjustment in Timer 299 and it seems the DTMF is working.

Thanks again,

Jonnel
