As of version 126.96.36.199 It's one of the best cell SIP clients available being completely free and supports busy lamp fields (BLF support is pretty much non-existent even and all the pay for apps I've tested). Its sorely needing video call Support and a fix for the mic not transferring to ear buds when they're plugged in (only speaker transfers). Mic in general I'm told is often too quiet on the other end as well, input gain setting would be nice, I'm not told this with other SIP client I use on the same phone.
LOVE The App Mostly So far I love this app and it works great with our SIP lines at work. My only request would be able to turn off it showing call history from the cell phone line. I wish I could only see the calls made through GS Wave in the history as they are all my work calls. Personal calls are made through my cell phone. If that could be an option, then this would definitely be a 5 star app.
I could not properly test it because I could not change the SIp port from 5060 to the one I need. Whenever this setting will be available I will be able to test GS Wave mainly looking at how it goes through NAT, as this is a big issue with other SIp clinets. I am looking forward to being able to test it. I only gave 3 stars as a neutral mark. I did send an email to the developer yesterday but I have not received any response yet. I basically need a SIP client that can smoothly go through NAT so I can have the voice packets handled correctly, a client that will not take 15-20 sec after I hanged up to close the call, and one that would not drain the battery faster than expected. I trully hope this SIP client is the one I am after, but, as I said, I was not able to test it due to not being able to change teh SIP port from 5060 to the one I need.
The best soft phone and I have tried them all Only issue I have is call waiting while I am on a cell call I wish h I would have call notification so I can put the cell On hold or hang up and switch to wave to answer the call. Right now its just declines the incoming call while I am on a cell call. This should be changed these days voip calls have higher priority than cell and it's possible on other soft phones like z.... on Android
Am I missing something? All is good, but incoming calls caller ID shows but is not integrated with my phones contacts e.g. Incoming calls says (Indianapolis, IN) as where my contacts name should show (Jack). It's there anyway to integrate the 2?
Too many audio issues In the past weeks myself and twenty+ users have experienced growing issues with microphone problems. Mostly the microphones on the Android devices not working. The same phones work fine with other sip clients and it's a shame because we use the Grandstream ucm pbx units in multiple offices. I wish the application worked more steadily.
