thanks for the reply. the DN is not shared or monitored. any other ideas?

telephony-service

hunt-group logout HLog

Hope this helps, please rate post if it does!

that is already configured. other phones in the hunt group can log out successfully, it seems to be limited to this one phone, and I can't see any configuration differences (aside from the DN etc).

Pls check output of show ephone. You might be monitoring the DN without knowing that.

i did, it is not monitored ther eis only the mwi. there is one thing that i have found, and please tell me if this is significant:

all phones where Hlog work are not dual-line DNs, but the one phone where it does not is a dual-line DN. do you know if this may be the cause? Is there a problem with dual-line DNs and hunt groups or HLog in general?

No issue with dual-line and ephone-hunt. In fact, in most cases you need dual line, to be able to do consultive transfers to other people.

Which exact phone FW do you have on that phone ?

SCCP41.8-0-4SR2S.loads

It should be SCCP 8.x on CME 4.0.3

FW should be fine.

I can't find in the doc anything against having single-line and dual-line in the same router, yet I would give a try making it single-line as well. After that only a very patient looking at the whole config could reveal something.

I had the same problem and resolved it by deleting the affected ephone-dn and recreated it.

Try

conf t

telephony-service

no cnf-file

create cnf-files

and restart the phone. That worked for me when I had the same issue.

Sorry about that it's
