Hello nmr6130,
welcome to the Polycom Community.
- Have you tested calling each other from these phones or is it only external calls that have one way audio?
- Have you excluded the handsets being defective by answering a call via the speaker phone?
- Have you got any other Polycom phones in your network?
- Have these phones ever worked?
- Have you tried dialing the IP address of the other phone to exclude Server / Firewall issues?
Please ensure to provide some feedback if this reply has helped you so other users can profit from your experience.
Best Regards
Steffen Baier
Polycom Global Services
