Registration failed - SIP Trunk

[Mehran Meidani]

Hi,
I got this message after I purchase license and upgrade from evolution to pro version:

 [CM504005]: Registration failed for: Lc:10001(@5191030xxx[<sip:[email protected]:5060>]); Cause: There's no Contact in response from server

Any idea?

Run the firewall check.
Contact your provider to see if they are receiving a registration attempt and if so to what "address" are they to reply. Is that address (yours) correct?

Hi Leejor,
I've already run firewall check, everything works as expected. Despite of registration failure, incoming calls from sip trunks works! I'll let you know when I've checked the address from the provider.
Thanks.
