CS1000E Rel 4.5 - SIP Trunk - No SIP Info messages for DTMF

[FinnSloss]

Hi there,

I am trying to get DTMF tones to pass SIP info messages over a SIP trunk, without success!

There are 3 systems that talk to each other via SIP:
A CS1000T Rel 4.5
A CS1000E Rel 4.5
A Server with some Dialogic software (SIP endpoint).

Does anyone know why there are no SIP Info messages seen (wireshark) when DTMF tones are sent. Is there an option somewhere in the CS1000 configuration to turn this feature on?
Is there a software patch on the CS1000 that is required?

Any help greatly appreciated.

Thanks,
Finn

Can anyone shed any light on why there are no SIP Info messages being sent for DTMF tones? I cannot see them when doing a SIPCallTrace on the Sig Servers nor can they be seen on wireshark on the server endpoint. I've included the DCH and RDB below...

Thanks,
