we having issues with the 7920 wireless IP Phone that when we are calling from wireless to wired IP phone the call went through and we can hear voice; except that the voice is breaking.

However when we are calling from wireless phone to wireless phone; we are getting ring back tone and when we answer the call. the call connected and no voice at all.

do we have to upgrade the firmware or anything else needed??
