Hi,
Can anyone help? I'm not incredibly technical but have a vague understanding... using the CCA to setup, I know how to telnet into CLI but not confident on the commands to use after that so don't generally touch it so I don't break anything.
I've set up a SIP trunk on a UC540 from VOIP-Unlimited. The outgoing calls work fine, and have even set up the outbound DID mapping.
However can't get incoming calls to connect. I've checked that the IP addresses from the ITSP are all set to be allowed, and I've mapped the inbound DID to an extension. The error log includes the number formatted as both +44845.... and 0845.... so I've tried both on the inbound mapping but neither work.
The error code is 127, but after reading the Cisco document on incoming call problems can't work out what else to do?
Oh and I do have a Dynamic Public IP address which is being changed to a Static IP in the next few weeks if that makes a difference - but the error log shows the correct public IP address for my connection.
The error log is (I've starred out my phone numbers and public IP address):
