Thank you for Graham. I installed a Blink (a SIP app) on my test PC, it has
built in call recording function.
I have connected up my Grandstream HandyTone 503 and calls are perfectly
clear with no "blips". I can only assume I need to configure some settings
on the IP-01 or maybe I have some faulty hardware (unlikely).
Unfortunately my Asterisk knowledge is not that advanced. Is there anything
else I should look at?
Thank you for your help.
