DTMF problems

Hi there,

I am using ATA186 to connect Pager system to a CCM Cluster. When calling the Pager system and sending some digits (code) to it some digits get lost. If the digit are dialed slowly then it works.

Like if I dial 1010 (for the pager system) and then 2222 (for my pager) 123456789 (some code) the pager beeps but the code for example look like this 1237 instead of 123456789

I have configured the ATA AudioMode to get out-of-band DTMF (0x10151015) but it doesn´t help.

Any ideas ?

Re: DTMF problems

I dont know if this will help, but what are your gain and attenuation levels set at? I believe, if gain level is set 12 or higher there will be DTMF issues.
