3rd Party SIP endpoint vs Cisco IP handset

[Gurjinder Judge]

Hi,

Could someone help me to get some clarity on what features our client would loose if they decided to re-use their existing 3rd Party SIP devices rather than purchasing new Cisco IP Phones (e.g. 7841) on a new BE6K solution.

They would like to potentially register the following to their new BE6K

- Polycom IP 5000 conference phone

- Cisco SPA512G (believe this can only be registered as a SIP endpoint)

Help would be greatfully appreciated.

Thanks!

Hi Judge,

Couple of things I see here:

• If the 3-rd party device does not support Digest credentials then you have to have a DN in the UDS/LDAP and this can be messy for lots of users.
  

• Greater licesning cost for 3-rd party devices. (off set by purchasing new phones)
  
• de-centraliesed configuration of devices.
  
• no Integrated with Centralized TFTP, no Downloads Softkey File, does no Downloads Dial Plan File, no SRST support, no reset / restart support from CUCM GUI.
  
• DTMF considerations for interoprability.
  
• feature such as conf, call park, etc can be done providing that the 3-rd party has the firmware to support it.

Gurjinder,

The way you have to approach this is the other way around, define your requirements  first and THEN decide which phone ticks most of the boxes. also maybe assign a weight to each requirement (for instance cost might be really important in your case).

In general, 3rd party phones on cucm; very bareboned functionality; call and be called. they will be able to do SIP but none of the XML stuff like, CFWD all, softbuttons, directories etc.
