I have a UC540 with the PSTN as SIP only; no POTS used. About 10 DIDs registered with the phone company.
The goal is to have a bunch of individual DIDs but also group numbers like "sales" and "support" that certain phones can be on.
I set it up with the "Shared" button type on the phones, and then set up the inbound call routing to route calls to those shared extensions based on DNID. Also I set up the outbound CLID on those shared extensions so that people can call from the "sales" number instead of their own DID just by pressing that button before making a call.
Now what's happening is that it's working correctly, but if anybody has already answered a call on the "Sales" line, other calls to that line are going straight to voice mail until the first person has hung up the phone. So, it seems to have a limit of one simultaneous call even though there are other agents available to take the calls.
I guess that this isn't the "correct" way to implement shared lines like this? If that isn't, then what is?
Sorry to keep on replying to myself, but I got more information from the customer.
The problem that they are having is not with the shared line, but rather with a Call Blast group. And, the situation only comes up when two people call at once (ie, if Call A comes in, the blast group is still ringing when Call B calls, Call B will just get voicemail. If Call A gets answered and *then* Call B calls, it's fine).
From the Cisco documentation about Parallel Hunt Groups, I see that this is an expected situation in the case of SIP phones with call-waiting disabled. But actually all phones in the hunt group ar SCCP phones (SPA504G). Is there anything I can do to let more than one incoming call happen simultaneously?
Can you tell me what your Hunt Stop is set to on each DN please?
I suspect that might have been screwed up, from what I am reading into this your issue shouldn't be happening, but I also done fully understand the deployment so I am just making assumptions.
You can post your configuration as a text file with all the sensitive stuff removed and I can at least have a look, but if there are any changes required it would be more appropriate to try and do it through CCA rather then CLI.
