[asterisk-users] DTMF problems

[Kohler, Jeffrey]

I'm having problems where touch tones are being misinterpreted.

 

I have a setup where one user can dial out through Asterisk to second
user's telephone.

 

(User1 - real phone - VOIP provider - Asterisk - VOIP provider - real
phone - user2)

 

My problem occurs when you need to dial an extension or navigate a phone
tree to reach the second user.  When the first user uses their telephone
keypad to enter the extension, their keypresses are often misinterpreted
by the second user's phone system.

 

I'm wondering if poor sound quality could cause the tones to become
altered?  Any ideas or suggestions?
