PortSIP Softphone is a SIP-based softphone application designed for iPhone. It utilizes Wi-Fi or 4G/LTE connections to enable users to make and receive calls and instant messages.

When integrated with PortSIP PBX, PortSIP Softphone supports push notifications, allowing users to receive calls and messages even when the application is force terminated.

With access to the iPhone's contact list, PortSIP Softphone offers a user-friendly interface for efficient communication management. It supports multiple calls, enabling users to switch between calls, merge and split calls, and perform attended and unattended transfers. Additionally, it supports video conferences with MCU (Multipoint Control Unit) support.

PortSIP Softphone prioritizes security and incorporates advanced settings for secure call signaling and audio encryption.

The application supports high-definition video calls up to 1080P with H.264 and VP8 codecs and ensures high-quality audio calls. The supported codecs include G.279, G.711a/u, Opus, AMR, AMR-WB, G.722.1, iLBC, GSM, and SPEEX-WB.

Great soft phone! Needs stats please.

Excellent soft phone!! One of the best I have tried yet. Also privacy oriented. Don’t change. We use both with PortSIP pbx other pbx. Having 2+ sip accounts would be helpful.

Please add to the in-call screen: codec and Transport plus SRTP. G.711 TLS SRTP🔒 in the corner for example. Also it seems background noise is much clearer and picked up vs using the iOS dialer. Is there a noise cancelling on/off option for developers? Thanks!!

Finally, It Just Works!

Wow, a soft phone that actually works! Even in the background and when screen is locked. I’ve been searching for 2 years to find something this good. Thank you for not charging high subscription costs or bogging the app down with ads. The only thing I’d like to see added is multiple SIP accounts, but that’s just nice to have. Great job.
