Odd, the friend I have mentioned in other posts, who has embarked on  
this whole learning asterisk adventure along with me, is also using  
telesip and does not have any problems at all in this regard.  He has  
done some extensive IVR development, using agi to build some fairly  
complex directory and home-automation menus, and has enjoyed rock- 
solid dtmf recognition even when calling into his pbx from a  
cellphone over the telasip DID.  *shrug*

AFAIK, it is not a possibility with them, but thank you for the  
suggestion.

I have a GoIAX DID (which I thought was non-functional until I tested  
it a moment ago -- if it stays up, I will switch to using it as my  
primary) that seems to work a little better, but it is still not 100%.
