AS5350 DTMF works fine from external but not from PBX

ahoude333 · ‎10-21-2008

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.

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.
