The biggest problem is you really can't leave this on. I hate that Android got rid of the native SIP dialer because this client does not come anywhere close. If you leave the app running in the background overnight it will drain your battery. It's completely unacceptable for a sip client for people who run their own voice service. Just overnight my battery went from 65% to 1% between 11:00 at night and 5:30 in the morning with the app taking a whopping 40% of the battery drain.

One of the best softphone apps I've found. I love the clean and simple UI. However it's missing a feature that would be useful to me: configurable dialing rules and/or home country selection. My service provider requires all (US) calls to be prefixed with 1, which is sometimes present and sometimes not in my Contacts.

Thanks for your review. We already have the dialing rules feature in its basic form (it is called Number rewriting in the Account settings), but currently it can't be used to add a prefix. We promise to address this shortcoming in future releases of Sipnetic.

Great app. The mute and hold button placement is unfortunate. They are placed close to the area where you easily touch and activate them with an ear during the phone call.
