What steps will reproduce the problem?
1. I have one Android device with IMSDroid. I have two another SIP softwares 
(PJSIP under Linux). OpenIMS is the SIP server.
2. I begin making a call between IMSDroid and one PJSIP software. Next I ask 
for a call transfer from the PJSIP software to the other.
3. All appears to be OK. IMSdroid is asking me if I agree with the call 
transfer, a new INVITE is sent and the new call is established. But at the end 
of I have no voice in one way (from IMSDroid to PJSIP).

What is the expected output? What do you see instead?
What I can see is that Android device send no RTP packet but understand those 
received by PJSIP.
I tried with two Android devices with the same result. I tried replacing 
IMSDroid with a third PJSIP software and it is working.

What version of the product are you using? On what operating system?
I am using r585 revision of IMSDroid and PJSIP 2.4.

Please provide any additional information below.
Please find in attachment two pcap captures one is working (RTP in both ways 
after call transfer) and the other not.
