For a new low cost deployment, we would like to consider the option of third party SIP phones.
Our requirements are that the phones should have an extra ethernet port to connect the PCs. Preferably, the phones should support 2 lines.
Can you please give some recommendations based on your experience for some third party phones ?
Appreciate your time and help!!!
My experience - more work than it's worth
You will likely lose most features (why buy CallManager, pay licenses for each handset, and then not be guaranteed any compatibility on the handsets for features)?
You will lose easy management of firmware, and you will need to test each upgrade of CCM and handset firmware yourself...
Third party SIP handsets may be cheaper, but then... Asterisk is cheaper as well. If you don't intend to have a full Cisco solution it doesn't seem worth buying CallManager.
I would really only recommend using SIP handsets where/when I need to because those handsets can do something that a Cisco phone cannot.
