funkwerk IP50

Mini-Review of funkwerk IP50

This phone is also known as the Elmeg IP50

Pros

• Fantastic build Quality
• Solid plastic buttons – no rubber (except menu buttons) here
• A great phone for people unused to having to press “OK” with SIP
• Speakerphone is good

Cons

• Slow registration and “qualify” with Asterisk (compared to other phones on my networks – I am privileged to have my own private Asterisk server on a public IP with many private extensions, sitting in a data centre on a 40GB/s backplane).
• Ringtones inspired by a child’s music box (except the default) – The plastic buttons are fit for a builder, so the ringtones should be loud and harsh enough to hear from 30m away.
• Dates displayed in US format
• Poor documentation (I have found some extra undocumented stuff through telnet) – Manual seems to be technically incorrect.
• Telnet connection is not reliable
• Reboot required on practically every change on the web interface – though not always through telnet
• Compared to Snom 360 and factory N95 very unreliable on low speed ADSL connections (i.e. 800kbps downstream 400 upstream ) – It’s still slow on a fast connection.

e.g.

This is from the datacentre

ext 321 is another funkwerk / elmeg IP50 at the same location as _headoffice (which is a Pentium 400Mhz Asterisk server)
ext 308 is a Snom320 at a heavily loaded location
ext 314 is a hacked BT home hub to FXS conversion BT Home Hub as FXS
ext 320 is at the 800/400 location
ext 301 is a Snom 190 at the same location as _headoffice
