I am having problems with AS5300’s conectted to an Ericson AXE-10 via 4 T-1’s. The DS0-Group is set to e&m-fgb DTMF. About 30% of my calls go “high and dry” but the AXE-10 sees the 5300’s signaling bits go “high” indicating Answer Supervision. Is this a signaling issue between the AXE-10 and the 5300 or has the call been answered and only a one way talk path established?
Any help would be appreciated.
