I’m engaged on a voip app for android and IOS utilizing flutter. I’m utilizing dart sip_ua. I’m able to register to the signaling server in addition to obtain a name. The consumer can also be in a position to connect with the ice server. Nonetheless, the decision terminstes after 30 seconds with the error rtp timeout. Under is the error log:

Kindly assist with this.I’m new to flutter however i’ve expertise with webrct on javascript.
I attempted altering the ice servers and as effectively examined the ice server connection to verify the ice servers are working in addition to the signalling servers.
