Which handset are you using? Thanks, Srivatsan D Senthil wrote: Hi Attila, I'm developing a windows desktop SIP phone application using PJSUA. I'm facing the the same problem as you mentioned in your mail (i.e. "Underflow message in log and the remote party not able to hear clearly). I tried as you stated in your previous mail but no success. Any suggestion to improve the voice quality. Can you send me your modified config_site.h file; just want to double check what I missed. Any suggestion is greatly appreciated. Thanks & Regards, - Senthil Attila Nyers wrote: Hi!
