Hi - We have a a voice gateway which is being utilised for mobile calls. It is connected on E1 pri through PSTN to mobile company's ISDX using QSIG. We are utilising an existing 2600 H.323 gateway (config below) integrated with CCM 4.1. This has been workig fine in the past but now, although the calls connect - both parties calls connect, but the call is extremely distorted and only severe feedback is hear at both end.
Any help is greatly appreciated.
