In some calls I receive as answer from PBX the "603 Decline" message, waht is the cause for this message be presented?

Waht do I to review to solve the problem?

Thanks and Best Regards

check if there is any dial plan or ARS define 603 and
capture packets and check who sent 603

You may check a cause of 603 at SIP Server's Call Log page.
There is the [result] field which will indicate a cause.

Also, if a received SIP packet is invalid, the SIP Server will reject the packet with 603.

I recommend that you check the SIP Server's log.
