Hello Sir,
Hope you are doing well.
I have over 10+ years of experience with VOIP based phone systems based on the FreeSwitch including Asterisk PBX, Linphone, Softswitch, Jitsi, Webrtc, Mobile Dialer for Android, and iOS. and Windows PC Dialer. And hands-on experience working with 3rd party API Integration.
I have gone through your requirements and I feel confident enough to work with you on the same.
Would it be possible for you to come over chat to discuss further?
Awaiting your positive response.
Thank you.
