Hi All,
Acrobits has just placed its iOS apps for SIP services on sale for 50%. These
are:
• Groundwire - Business Caliber SIP Phone ($4.99, usually lists for $9.99) by

• Acrobits Softphone SIP phone for VoIP
Just as an endorsement, Groundwire is definitely a fantastic app and
completely accessible. It's a good buy at $4.99 and anybody who is using
VoIP calling would probably not regret getting it.
As Esther said, these apps all require subscriptions to VoIP providers and
there are too many out there
