DTMF problems "sometimes" with Asterisk + x-lite > features.conf

Zones: Asterisk Open Source Telephony, Voice Over IP

Tags: digium, Asterisk, 1.4, x-lite

Ok...

I have several features enabled in features.conf.
I also have relaxdtmf turned on.
My featuredigittimeout is 2400

When a user types a * then the number for the corresponding feature... it "sometimes" works...and "sometimes" doesn't work...

Increasing the console verbosity...to include DTMF debugging....

I see this...

Example of a user pressing *2...only the 2 is seen.

as you can see they tried it twice.....
Sometimes it works and sometimes not...and when it works you can see the asterisk " * " received on the CLI.

Basically *2 invokes a macro...that begins recording on that channel and saves the wav file to a specified directory. When the * is received the macro works perfectly...but obviously sometimes, when the * is not recieved by asterisk... no fun at all.

using # for transfer works consistently....

So what's up with this.... ? anyone ? any ideas ?

...I know xlite has some problems sending dtmf as well... and btw, i've tried inband, info, rfc2833, auto...changed on both the xlite and in sip.conf. Still no good, or worse. I've looked at hundreds of threads/forums.... and NOBODY seems to boast a REAL solution.

Forgot to mention I put back the SIPDtmfMode(rfc2833) in the dialplan...this could have contributed
