the remote phone book.

For the SIP-T40P/T40G IP phone, we recommend you to download less than 3000 remote
contacts from the remote server, and the size of a remote phone book file should be less than
750K.
For the T48S/T48G/T46S/T46G/T42S/T42G/T41S/T41P IP phones, we recommend you to
download less than 5000 remote contacts from the remote server, and the size of a remote
phone book file should be less than 1.5M.
If you disconnect the mobile phone from IP phone when the IP phone is updating the Mobile
