I have been using Xnet VFX for a few years now and have been trialling a line on 2talk with a view to moving over to the business service. Service works really well but was wondering how I can make sip uri calls via 2talk. Is this possible? Is this what trunking is about? How do other people have it setup?
Also I have been trying to find a SIP android app that works but having been through most of the apps only one seems to work properly, Sipdroid on my Android 2.3.4. Even sipdroid has the problem of sound coming out of the rear speaker as well so not having much success getting a reliable setup on Android. Rear speaker on seems to be a common problem but means echo for the caller.
Apologies if these seem like obvious questions but my knowledge on SIP is basic but growing.
