Is it possible to register with S4B as well as Cisco Call Manager? I have read a few posts regarding modifying config files, but it seems like there should be an easier way of doing this. Any help would be appriciated. (Group 500)
no, not possible. Group Series does not support Hybrid Registration (SIP & SfB). It´s only a feature for VVX and in Trio.
welcome to the Polycom Community.
At present only our Trio Range supports a dual registration with Skype for Business and up to 2 additional SIP registrations.
The VVX is either Skype or SIP only.
The GroupSeries is Skype or SIP and in addition H.323

Its not directly intgerated. What you can do integrate the SfB with CUCM and then configure the GS with SfB with this you can call both CUCM Extn and SfB Id.
