## Description

PortSIP UC is a SIP-based softphone for iPhone that lets you make and receive voice and video calls, and chat, over Wi-Fi or cellular networks. When used with PortSIP PBX, it supports push notifications, so you stay connected even when the app is terminated. It can access your contacts for quick calling and messaging, and supports multi-call, call hold, switch, merge/split, and attended or unattended transfers.

For video, PortSIP UC supports HD up to 1080p with H.264 and VP8, and uses a wide range of codecs including G.279, G.711a/u, Opus, AMR/AMR-WB, G.722.1, iLBC, GSM, and SPEEX-WB. It provides secure call signaling and audio encryption to protect your communications, and even supports MCU-based video conferencing.

## Review summary

PortSIP UC is generally praised as a reliable soft phone with easy server connections, background operation, and a privacy‑focused, ad‑free experience. Users highlight PBX compatibility and a dark theme. Common drawbacks include login reliability and UX issues, stability problems on newer iOS versions, call audio glitches, network/provider-specific connectivity bugs, and the lack of multiple SIP accounts.

### Pros

- Works in the background and stays connected even when the screen is locked
- Ad-free experience with no high subscription costs
- Privacy oriented design
- Easy server/SIP connectivity with PBX compatibility (works with PortSIP PBX and other PBXs)

### Cons

- Login/sign-in reliability and UX issues (slow auto-login, sign-in/in-progress states, login/logout confusion)
- Stability issues on newer iOS (crashes, startup hangs, or won't launch)
- Call audio problems (intermittent audio loss or one-way audio, server errors)
- Network/provider-specific connectivity issues (works on some networks but not others; issues with T-Mobile, US dialing)
- Single SIP account limitation; requests for multiple accounts
