Mixed TCH/F and TCH/H issues

Hi Andreas, We were testing TCH/H yesterday and stumbled upon an issue when a call is made between TCH/F and TCH/H. - When the call is from TCH/F to TCH/H, it doesn't connect. - When the call is from TCH/H to TCH/F, it connects, but voice quality is bad - sounds like 50% packet loss. Logs and localhost Wireshark captures of calls in both directions are here: http://ipse.chemeris.ru/osmo-captures/dumps.tar.xz Do you see what's wrong with them? Our configuration was * Dual-TRX with 1 TCH/F and 14 TCH/H channels. We have to keep some TCH/F channels, since there are old phones which doesn't support TCH/H. * Codecs enabled were FR, AFS and AHS. * LCR was connected to the MNCC socket, but in the case of TCH/F->TCH/H call I didn't see it coming to LCR at all. -- Regards, Alexander Chemeris.
