            Media Attribute (a): fmtp:101 0-16

 Is it happening for the ACK you pasted or some other message?
It only happen on ACK messages, when my client reply 200 OK /SDP to server to establish call.

For more detail: I use another soft phone on Android like Zoiper and test with the same scenario, it work ok. And when my client use 3G, it still work ok.

Hi all,

I have problem when make call with my Android mobile use PJSIP library.
Scenario:

my client  -> Kamailio -> Freeswitch (media server) -> another client (soft phone on Windows)

my client:
 + use Bluestack
 + Capture via Wireshark
 + use Wifi

Issue: The call will be drop after ~ 30 second.

I see the error on Kamailio:

I think the SIP message is fragmented but when resume package is not correct.
Do you have any advice ? Thank you for watching !
