Hi,
I am a developer and VoIP, Telecom, and Linux expert from Pakistan. My solid command with SIP, IAX2, H323, SMPP, SMTP, XMPP, SIMPLE, T.38, and WebRTC allows me to develop Voice, SMS, Fax, and Email related applications.
Please let me know the details of the project or contact me to discuss how you want to proceed.
Regards
