Sip Voip Problems Bad Sound Quality
I have severe problems with Sip/Voip, almost any softphone and the android sip client are giving a lot of echo and ticking sounds while speaking. Also if I switch back to the stock Rom slot running stock JB from Verizon the problems are the same. So I don't think it is about the Rom (CM10,1.2).
The only client that seems work seemly fair is the SipDroid client, while the FritzBox Fon App is working perfectly. The engine of this client is also based on the SipDroid client.
On my stock rom I haven't installed the FritzBox fon app, so It can't be interference of both.
I hope somebody does have an suggestion, because on my old nokia E72 voip was running very smooth, even on 2G GPRS connection through a VPN tunnel, crystal clear sound.
