+jiri's SIP phone shopping list
|
|
|
+------------------------------
|
|
|
+
|
|
|
+This is Jiri's list of wishes for SIP "hardphones". When there is such
|
|
|
+a phone, I will be glad to test it, promote it, and praise the vendor.
|
|
|
+
|
|
|
+I) MUSTs
|
|
|
+
|
|
|
+Without MUSTs, I will not like the phone.
|
|
|
+
|
|
|
+- Price - get it bellow $100 (I mean for one phone, not for 10.000 of them)
|
|
|
+- NAT-Traversal support: STUN, symmetric communication
|
|
|
+- DNS fail-over, as required by specification (I'm aware of only one phones
|
|
|
+ which is getting it right today, 2003-02)
|
|
|
+- REFER (correctly please)
|
|
|
+- reasonable provisioning
|
|
|
+
|
|
|
+II) RECOMMENDED
|
|
|
+
|
|
|
+With RECOMMENDED, I will do like the phone.
|
|
|
+
|
|
|
+- multiple lines
|
|
|
+- multiple calls
|
|
|
+- DTMF
|
|
|
+
|
|
|
+III) SHOULD
|
|
|
+
|
|
|
+With SHOULDs, I will fall in love with it.
|
|
|
+
|
|
|
+- GIPS codec is good
|
|
|
+- power-Ethernet
|
|
|
+- desktop features: deny incoming call, DnD, 3-rd party conferencing,
|
|
|
+ auto-repeat of failed call attempts
|
|
|
+- well-readable display, at best backlit
|
|
|
+- solid robust design, like with the PBX phones from well-established
|
|
|
+ PBX vendors
|
|
|
+
|
|
|
+Note there are other lists too -- Henry Sinnreich's draft provides a great
|
|
|
+dictate to phone vendors.

|
|
+
|
|
|
+KNOWN ERRORs
|
|
|
+------------
|
|
|
+These are errors we observed frequently to fail in phones: digest/qop,
|
|
|
+DNS fail-over, REFER, transaction matching, record-routing.
