AS5350 DTMF works fine from external but not from PBX

Unanswered Question
Oct 21st, 2008

When calling into from an external Phone line (Cell phone,etc) the DTMF works great, every time.

From my office using a ROLM phone dialing out into the Gateway it picks up fine, but the DTMF tones are not recognized but sometimes it is. It is intermittent. I suspect an IOS level related issue. If this is the fix, can you informed me of what IOS level is required to fix the DTMF problem using a PBX.

See attachments for version and running-config.

The IOS version is Experiemental Version as it appears, Can you try a stable Validated IOS

Lets say 12.3(11)T7 for example

Can I use c5350-is-mz.124-6.T11.bin ? And if I can, do I need to install another boot flash file or can I use whatever I have.

I believe I have only 32mb of flash. Will the above IOS be ok to use?

Thanks for all your help.
