CS1K IP-SIP 1

[reisve]

Hi
I have a customer with a CS1K Rel 7.6 with TDM licences. The customer wants to upgrade to VoIP, and would like to convert the licences to SIP 3rd party, and use Yealink phones.

The vendor is teling me that the 3rd party SIP phones will not have all the features. Can anyone explain me which features will not be available if he buys YeaLink phones?

Thank You

Upgrade the whole switch to an E-MetroTel UCx legacy Nortel IP switch and be done with it! You can use the Nortel Unistim/Nortel SIP phones, Nortel M2000/M3900/ Norstar/BCM T and M series digital telephones, and any third party SIP extension such as a Yealink or Cisco SIP set, all while keeping your Nortel products. That's just my two cents.

If that isn't an option, don't get rid of the Nortel CS1000 equipment. Add the Unistim IP sets....they are by far the most reliable IP sets on the Market.
