receive busy signal then play busy tone by ip phone
Hi, I got a problem.
My customer use callmanager 6.1 and ip phone 7941,3845 Voice Gateway use E1 PRI connect to 2 PSTN Provider CHT by 4 E1 and MKY by 1 E1.
When user call out to PSTN phone by CHT if the called phone is talking to someone then CHT will reply busy tone to 7941 so caller can hear busy tone that is fine, but if call out to PSTN phone by MKY, it just reply busy signal not busy tone so 7941 cann't hear any sound.
How to setup IPT when receive busy signal then play busy tone to 7914?
