I have CME 4.0 on a 2801 with 12.4(4)XC ipvoice and 7 channels of a T1 ISDN PRI on an mft card. On my 7970 phones, which are running the latest code, when I make outbound calls to the PSTN I hear a short lived static sound usually during the beginning of the call, but often at intervals during a conversation. I have searched this forum but cannot seem to find anyone with a similiar issue. I have included relevant portions of my config. Recommendations welcome:
I do not dee your DSP resources and I thought you can not do voice on a 2801 the processor power is too weak. I have seen this issue in FXO ports and the DSP was bad also use a T train IOS 12.4(3b) is also a good one.
