Hi, All
I have a mixed CME network with 7912s and 3911 on a 2811, with IOS 12.4(15)T and CME 4.1 and 8.1.3 Firmware for 3911, the 2811 has FOX connections to PSTN. When 3911 are calling or receiving calls from PSTN the voice gets cut off and comes back again on and on, has any one ever face such a problem. this happens for all 3911s and only 3911s the 7912s work fine. 7912s are working with SCCP by the way.
