I remember correctly, but preferably use the pchan
type
TCH/F_TCH/H_PDCH in your osmo-bsc or osmo-nitb config.
As per the channel configuration defined in the code TCH/F_PDCH is a valid channel
configuration and it should work as TCH/F or PDCH channel dynamically.
I tested even with TCH/F_TCH/H_PDCH and it works fine only as TCH/H or PDCH it does not
get used as TCH/F.
When you refer to a PS call, do you mean that GPRS
service is used to place a
VoIP call? This is the same as saying that GPRS is functional.
By PS call I mean GPRS data transfer and yes GPRS is functional.
Please verify your statements and/or accompany with
log output, and also
try TCH/F_TCH/H_PDCH instead.
I have tested TCH/F_TCH/H_PDCH also and it works fine as TCH/H channel. As per the name of
the pchan type it can be used as TCH/F or TCH/H or PDCH
But it does not work as TCH/F.
Also as I mentioned earlier in TCH/F_PDCH pchan type CS (voice) call does not work.
If the problem persists, please a) bisect to pinpoint
the failing revision and
b) add full log output, preferably with DRSL and DNM logs set to debug level.
Currently I am busy in other activities. I will bisect and capture the logs once I have
some time . Could you please suggest any specific Unit test case which can be
executed to compare result.
