When I am calling to numbers which is to be reached accross H.323 Voice Gateway (1751-V, c1700-ipvoice-mz.123-7.XR3.bin) all is OK. But, incoming call on that gateway can be placed only one time after making outgoing call on that gateway.
IP phone - CCM - Voice Gateway - ISDN works OK
PSTN - voice gateway - CCM - IP phone can be placed only one time if previously make outgoing call.
For connection to Telco Voice Gateway (with VIC-2B-NT/TE) use ISDN BRI.
I have read about this problem, but now I can't to find now. Can anybody suggest me any idea about this problem?
