SessionTalk Pro Softphone

The app works pretty well - better than any other VoIP Softphone I’ve tried. iOS call kit integration is its main selling point for me. There’s a few times though where conference calls don’t connect properly (some callers can hear each other but other times they can’t - requires the call to be ended and started again). It also interrupts music playback a bit for reasons I’m a bit unsure about... its like a fake call is started and then hangs up (so with my Bluetooth headphones it stops playback because it thinks a call is coming through).

Wonderful

Excellent product but needs persistent volume settings. Have raised this issue with developer.

Easy to configure. Supports multiple providers and seamlessly reads my address book. Use it extensively when travelling. Had the free version for a couple of years, but then the functionality was throttled so I had to upgrade. Had been using the Pennytel (free) version for a couple of years, but that stopped working under iO5 .

The app works as its suppose to, except sometimes doesn't work for too long after the app goes into the background and start using another app.

Looks good so far. some minor config issues reaching my asterisk server from outside the firewall. Connects ok but no audio... Will repost when I figure that put.

This app works well, but keeps GPRS up all of the time. This is handy if you want to turn your phone into a hand warmer, but not so good if you want your battery to last for more than a couple of hours.

Works seamlessly with ios 5.01

I tried a lot of similarly-priced softphones and this performed the best. Audio is a little glitchy but not so much as to be a problem. Good interface, quite stable, works in the background. Works well on the iPad too.

Very unhappy :( have to restart so many times to get the sip account to sync, also I can't add a prefix number to get a line out from my address book, and the Bluetooth setting doesn't save.
