| Description: | I often have terrible and trembling sound calling via asterisk. It took a long time to find out where the poblem is. I have 6 servers with asterisk installed and with E1 PRI (E100P, TE405P) card on board each. The problem presents on all mashines independently on hardware configuration. Debug information example: Call 1: Name: Zap/2-1 Type: Zap UniqueID: 1086092992.1819 Caller ID: 003717365955 DNID Digits: 148 State: Up (6) Rings: 0 NativeFormat: 72 WriteFormat: 8 ReadFormat: 8 NativeFormat SLINEAR | ALAW WriteFormat = ALAW ReadFormat = ALAW Sound quality is good Call 2: Name: Zap/1-1 Type: Zap UniqueID: 1086093184.0 Caller ID: 3717365955 DNID Digits: (N/A) State: Up (6) Rings: 0 NativeFormat: 72 WriteFormat: 64 ReadFormat: 8 NativeFormat SLINEAR | ALAW WriteFormat = SLINEAR ReadFormat = ALAW Sound quality bad. The example above shows that SLINEAR-coded data was written to PRI port. Why? If I take it right PRI port can receive only ALAW-coded data. | ||

By: Mark Spencer (markster) 2004-06-01 17:37:47 This is a hardware compatibility issue. | ||
