We have tested this app with Macally iVoiceIII external MIC.

(3) SKYPE is not sip protocol, so this app does not support SKYPE account.

(4) Some mobile network operators may prohibit or restrict the use of Voice over Internet Protocol (VoIP) functionality over their network, such as the use of VoIP telephony over a cellular network, and may also impose additional fees, or other charges in connection with VoIP. Please check with your service provider before you use SIP call over 3G or Edge network.

Now we have prefix for each account, the prefix for each account only works for calls made from address book.

When the per-account prefix is not set, the prefix in setting will be used, it works for all calls

Enjoying the app thus far. Haven’t had a chance to use it much. Wondering about the ability to dial direct extensions inside our sip network ?

Upgraded app. Lost all custom accounts... Now it won't let me click Next to set up a custom account. No joy... Will only recommend to people I dislike. Media5 phone app however just works...

Won't keep account active

Timiller1826 on

It worked great for many years. Now, I must reenter my account information each time I want to use it. This may be a result of developer not keeping up with updates.

New version 4.9 wouldn't save SIP settings. Rebooting seemed to have fixed it! Kudos to tech support for emailing me back!

DO NOT BUY BROKEN!!!

David in Africa on

This used to be a great app. The latest version has a clock problem, Either easy night it will delete all your data at 24:00 or any time it crashes, which is fairly frequent. Emails to tech support always go unanswered. Now after 3 weeks, I consider this a fraud! BEWARE!

New version keep deleting my account

JosTanSing on

Hi I have been using this apps for quite awhile. No problem till I use the latest version. Can you fix the bug in your program? My account is always being remove after I close the app. Thanks

Updating clears accounts

cheez puffs on

I had sip working fine, updated the app via App Store, all account settings are gone, I have to readd them. Time consuming, not worth the effort.
