Speakerphone quality on S700


Anyone experience poor quality sound when calling a S700 and the person has you on speaker phone? We have recently switched to using Sangoma phones from a mixture of Polycom and Aastra. I find when calling an extension (internal or external) I can hear a clipping just after I speak.

I’m not hearing my voice exactly, but I can tell the phone is trying to cancel it out. When the user goes off hook it clears up immediately.

Thank you,
