• In Unified CM 15 the External Presentation Number accepts up to 32 digits, with trailing X characters replaced by directory-number digits from right to left, and the External Presentation Name accepts up to 50 characters. in context
• In Unified CM, SIP trunk external presentation settings override SIP Profile settings, which in turn override directory number settings. in context
