DTMF transmission across VoIP campus 1

[ColinW]

Hi all,
I am interested to understand if any one has knowledge of any issues transmitting DTMF across an Avaya PBX Campus ( 3 sites) which uses S87XX servers and G650 cabinets. The key concern being the transmission of DTMR across the VoIP campus to centralised IVR systems. I am experincing lost DTMF digit receipt by the IVR?
Look forward to reading any responses.
Thanks

colin,
yes, DTMF will have problem only on the compressed voip traffic . so its not recommended to use DTMF transmiting over compressed VOIP some times the digits will not transmited properly , try to use uncompressd VOIP traffic to get all of the DTMF correctly inside the IVR aplication
