Hello,
I would like to implement a web-phone that should be able to communicate with different PBXs (Freeswitch, Asterisk, 3CX, etc.). I plan to use a SIP proxy where the communication between the web-phone and the proxy can be implemented via websockets and the communication between the proxy and the PBXs can be implemented via standard SIP (UDP/TCP).
What are the advantages/disadvantages of using the Janu's SIP Gateway instead of proxies like OpenSIPs and Kamailio?
Thank you in advance,
George
