How do I get Zioiper to set the DSCP field of the RTP packets?

Question

I have Zoiper on my Android phone talking to my FritzBox 7390 VOIP router.  When the FritzBox sends RTP packets, it sets the DSCP field in the IP header to give the packets high priority.  But ZoiPer is not doing the same thing in the RTP packets it is sending to the FritzBox, and possibly as a result of that, there is at times quite high packet loss in that direction (the FritzBox reports the statisitcs for each connection).  And the voice quality is quite variable and at times unintelligable.  So is there a way to get ZoiPer to set the DSCP bits?

Answer 1

There is no DSCP tagging in Zoiper for Android possible yet, it is on our todo list though.
