Need help with a Android SIP client over a 3G / 4G LTE networks - open to bidding

Hi!

I`m having problem with CSipSimple over 3G networks. Maybe it`s a firewall problem or a problem on the SIP server.

I`m using [url removed, login to view] because I want secure calls. It works great on very good internet connections, but over 3G it`s terrible. Maybe it`s a codec related issue and some SIP server issue.

Can you help me with it? I can pay you for hour, for example.

Thanks!
