Softphone versus Hardphone Vlan Constraint
|
|
| Nasser Khwaja 2005-09-23, 7:45 am |
| Hi,
I already have cisco IP Hard phones working within a VOICE VLAN together
with the CallManager, and the PCs in a DATA VLAN.
Now I need to install Softphones on PCs; and since these PCs are in the Data
Vlan subnet, my question is How do my cisco Softphones get the dialtone from
the CallManager which is in a separate Voice Vlan subnet?
Your response will be appreciated.
Thanks

| If you are routing between the data and voice vlans then there should
be no issue. If you are not routing between the two then that is a
problem.

| So the softphones are in the data vlan?
I would have imagined that they would make the PC behave like a true IP
phone: have a trunk to the switch, listen to the CDP advertisement of the
voice VLAN, and tag the outgoing voice packets with it (leaving the data
packets untagged)...
Now wouldn't that be nice?

| While that would be a neat feature you'd have to have a NIC with the
ability to handle the dot1q tagged packets. I'm sure this would
prevent most laptop users from using the software.
