Hi Jason,

The caller may not receive a 200OK message to inform that the W52P has answered the call in time or some parameter change in the call process which. Can you please provide below information

1. If you call the W52P from an internal phone the problem won't occur?
2. It never happens when you make out a call?
3. What's the PBX serve the W52P is registered?
4. What's the firmware of W52P? Can you upgrade to latest firmware and check again.

5. If the problem persist, please get a pcap trace, level 6 syslog and config.bin. The post describe how to collect them.
