Cisco Jabber 11.1 one way voice issue in iphone

[shahulhameed]

Dear Friends

My manager is in USA. Cisco Jabber 11.1 has installed on his phone. The configuration in CCM is fine and it is registered. The problem is if I call him he can listen my voice but I couldn't here his voice. I test with other iPhone with same account it is working fine.

What could be the problem if I call WhatsApp or other voice service working fine on his phone.

Please advice how can I resolve this issue. If voice setting problem in iPhone how can I check I don't have much experience iPhone.

Thanks and Regards,

Shahul Hameed.

I suspect, and this is really just a guess based on your description, the network that your manager's iPhone is attached to is not able to route back to you.

1-Way audio almost always comes down to routing. Is his iPhone connected to WiFi and if so, is it the same SSID as the iPhone that is working?

I assume these are internally registered clients and they are not traversing Expressway externally?

Thanks,

Ryan

Dear Friends

Thanks for your suggestion. 

Same ID I checked with another iPhone it is working fine. Also check with local Wifi and outside network for other phone working fine. I suspect about his phone setting may be mute or sound but we tried reset Jabber and uninstall reinstalled it, no success result.

here is what needs to be done;

goto iPhone settings\ Privacy\and make sure Cisco Jabber is checked for "access to microphone".

- rate if this helps.

Pls try capture wireshark on PC with jabber win by making call from jabber iphone to jabber win in softphone mode 

then use wireshark filter sip||rtp to check for issues...

anywhere in the topology do you see an ASA/firewall coming into picture ? If yes has it got sip inspect enabled ?
