[Asterisk-Users] Pb DTMF with Asterisk vs Cirpack Transit Node

[Guy Decarpentrie]

Hi all,

I've a problem in DTMF dialog between * and  a Cicpack Transit Node Class 4-5.
The call initiat by a mgcp phone pass by the cirpack and arrive in SIP on *, 
everything is ok (negociation and phone call) but when we try to use the 
voicemail, Asterisk don't understand DTMF.

Here are some logs (SIP debug on) on a DTMF '2' receive :
