[Lelio Fulgenzi]

until those of us with Residence rooms that use packetshapers find that phones are not downloading software. ;)

BitTorrent would be an awesome choice of protocol, methinks. The more phones you have, the faster they’d load.

well, considering Connection does directory updates via SMTP, you never know what might happen.

Anything not released is roadmap and under NDA. I've not heard any ftp discussions but I have heard other transfer protocols discussed.

I wonder if there are any long term plans to switch from tftp to ftp as phone image files keep growing larger…..seems a phone across a slow wan shouldn’t take 15-20 minutes to upgrade a 9MB image. I switched to ftp/http for router upgrades years ago as it was almost twice as fast. Wish the phones would change from tftp to ftp or http, etc. 



TFTP benefits 

Small footprint client 



TFTP limitations 

ACK every packet 

512 byte packet size maximum 



FTP benefits 

1500 byte packets 

Scaling windows TCP, etc 

No real drawbacks except client footprint is larger
