Hello Everybody, I am very good with Asterisk and I have been in computer telephony for many years, and I am tired of having to deal with the huge costs of third party softphone libraries and I have decided to finally write my very own softphone from scratch!... I mean, it is ok for anyone to charge what they want for their work, don?t get me wrong I just believe that if I am in the business of CTI, I ought to do this from scratch, since it does not make business sense for me to offer a software package in which the customer has to pay for 2 developers. I will appreciate if you can please inform about the following: 1) Is pjsip entirely in C??, isn?t there an API to use with maybe Microsoft?s C# ?? 2) Is there anybody that maybe sell me OCX or DLL I can use ?, I am a vb.net programmer. 3) Being a vb.net programmer, what are my choices to use pjsip? (other that learn GNU C)? Thanks for your answers C.

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!
