I increased its memory size in GNS3: After a reload, things went ok I also reduced the max-ephone and max-dn values: Now we can add ephone-dns without problems: When I create a dual-line ephone-dn, two “sub-ephone-dn” are created: To verify ephone-dns: another way to verify it: Notice that there are two channels for ephone-dn 2, which is a dual-line ephone-dn.

Adding a secondary line to a dual-line ephone-dn:
