I’m relatively new to Cisco technologies and have been working on configuring SIP trunking between a CUBE (Cisco Unified Border Element) and CUCM (Cisco Unified Communications Manager) and also between a CUBE (Cisco Unified Border Element) and the Service Provider . I followed the Cisco white papers and documentation to set up the configuration, but I’m facing an issue where:
-
Outbound calls from internal extensions are not going out.
-
Inbound calls from outside cannot reach our internal extensions.
I have already gathered and uploaded the following:
Here’s a brief overview of my setup:
-
CUBE Version: Cisco IOS XE Software, Version 17.03.04a
Cisco IOS Software [Amsterdam], ISR Software (X86_64_LINUX_IOSD-UNIVERSALK9-M), Version 17.3.4a, RELEASE SOFTWARE (fc3)
-
CUCM Version: System version: 14.0.1.10000-20
-
SIP Provider: BSNL
I’ve double-checked the configuration against the Cisco documentation, but I’m clearly missing something. Could someone please review my configuration and logs to help identify the issue?
