I have implemented Asterisk SIP server & I am able to make call using Android SIP UA.
The problem is when the DSL modem restart, the public IP changes & the same need to be modified in the SIP UA so that UA can do the registration again.
How can we avoid changing SIP server public IP in SIP UA again & again ?
Is it possible to configure a SIP URI ? If yes, how will the SIP server URI & new public IP mapping happen.
Kindly share the detailed procedure,
