Reply To: GERAN feature package 1 problem


it seems to point to an AMR problem… (hurray !)
I’m not familiar with siemens, but do you think there is any parameter that could cause such a weird behaviour?

I don’t think so. Therefore I would tend to assume that either 3GPP or Siemens did a mistake somewhere.

Or perhaps it is still a problem with DTX ? Can you try to disable UL DTX for AMR calls ? that might improve the situation…
