Since the latest Jabber 9.6 Update for Android, Voice is only working one-way any more on Samsung S5 - i cannot hear the person talking to me, but the other person can hear me.
The client got already completely re-installed but the issue is still in place.
Is there some change on Server-Side required or is the new Jabber Client simply no longer working on S5? (the old worked....)
there are a few things that might be the case;
-> Jabber for android is not tested with Samsung galaxy S5 as of now; here is a list of phones that should work well; http://www.cisco.com/c/en/us/td/docs/voice_ip_comm/jabber/Android/9_6/RN/JABA_BK_JC9A5408_00_jabber-android-release-notes-9-6.html#JABI_RF_HD6503B0_00
The device must be able to access the corporate network in order to use audio and video capabilities.
Also in order to make sure that this is not an issue with the network; can you get this tested with a supported phone as listed above to see if the audio works both ways.
Please rate if this helps.
I know that release notes but as mentioned:
it worked with Samsung S5 with the previous version of Jabber for Android - so where is the sense of changing a client that it doesn't work any more on a current Phone and to support only old devices?
Try disabling WMM support on SSID , which will eventually disable 11n data rates. Seems to be some issue with Samsung on 11n . You may try this , it might work for you.
In the CUCM Device page, could you confirm the IP address used by Jabber to register with CUCM? Also, please check signalling and verify the IP address used.
The 4.4 version of Android is having a defect, due to which applications use the source IP address of the 3G or Wi-fi Interface when it is connected over VPN.
Due to this, the other end cannot route the RTP stream and one way audio issue occurs. This is a Google defect, yet to be fixed.
