[Asterisk-Users] Outgoing voice distortion with Unicall

[Anton Krall]

If the voice distortion sounds like "clack clack clack" las if you had a fan
right next to you (remember when you talk directly to a fan in front of you,
the other side gets your voice like in intervals), if that’s the case,
exactly, your frame size should be 20ms, sipura and some other atas come by
default with 30 packet sizes, after changing to 20, all worked fine.

Hope that helps.

|Hi,

|I had similar problem and problem was in SIP ATA device (we

|frame, when we change frame to 20ms everything work perfectly.
