[Asterisk-Users] Swissvoice ip10s MGCP questions and experiences

[Philipp von Klitzing]

Hi there,

here some questions and experiences after playing for one day with 3 
Swissvoice ip10s and the latest * CVS:

QUESTIONS:
- what is the user option "enter voice mail number" good for? It doesn't 
appear to be of any practical use
- does anyone have some Swissvoice info that I cannot find on their web 
site like the guide to MGCP XML (.svd), guide to configuration file 
format (.cfg), guide to phone configuration through TELNET?
- do I need two lines ("aaln/1" and "aaln/2") or just one in my mgcp.conf 
(since the ip10 appears to support two lines)?
- are there any specs available for the format of the operator/ user 
logo? Must this be b/w, or can it be greyscale (2 bit/ 4 bit/ 8 bit?). As 
I understand both .gif and .jpg are fine. Pixel size?
- how can I obtain newer firmware that hopefully solves my crash problem?

WORKING:
- simple calls, phone book, hands-free
- MWI: F4 key lights up when messages are available
- pick-up: Assign the pick-up function together with *6 to F2.
- assign FLASHING to F1
- DoNotDisturb (on F3) works as expected
- blind transfer using #

NOT or PARTIALLY WORKING:
- I can only set the "phone name" via display --> free idle text?
- with F4 configured as voicemail function: pressing that key dials "#" 
and I must modify extension.conf to point # to VoiceMailMain2? Is there 
no way to change the number dialed by the voicemail button?
- MWI: the button lights up/extinguishes only when some kind of phone 
activity occurs; without any activity it might actually indicate wrong 
info (e.g. when user already check vm via web)
- during startup the phone nicely display the "waiting for call agent" 
message; however when the call agent (call manager?) * disappears 
afterwards the phones do not display that waiting message... :-(
- is there any way to make the "service key" do anything useful? 
Currently it has no function at all.
- crash: let the two ip10 ring the third ip10 at the same time (without 
lifting the handset) - in the moment the 2nd phone is calling the third 
phone crashes and must be rebooted. I can reproduce this 100% with any of 
the three phones. :-(
- the three call forward (CF) functions that can be assigned to the 
function keys F1-F4 don't appear to be useful. Instead of arrange an 
internal phone call forward this will immediately (!) dial the forward 
number entered at the very moment this function is activiated.
- I can successfully use FLASHING (F1) for consultative transfer, however 
I get into bad trouble if the consulted extension does not like to take 
the call and hangs up --> there is apparently no way to get back to my 
original caller, although I see both lines in the display and can move my 
cursor up and down on them. This might also be an * problem.
- web interface: "save current phone settings as profile" doesn't appear 
to be working, I see only 1 line displayed
- despite the seemingly permitted nat=yes entry I so far found no way to 
get this phone working from behind NAT (I know that MGCP as such probably 
will never work behind NAT, but still... by the way there is a new RFC on 
the road to attack this issue...)

NOTES:
- always restart (not reload) Asterisk after modifying mgcp.conf!
- mgcp.conf doesn't like the following keywords:
    disallow=
    allow=
    callwaitingcallerid=
    fromuser=
- the display is fine and equipped with nice logos, icons etc. The only 
thing that it is missing is the backlight, but I guess I can live with 
that...
- the menu is well organized and easily understood and navigated
- I don't think it is acceptable to only include a single A5 sheet of 
paper and not have ANY other printed user documentation shipped with 
the phone. A web-based PDF is ok, but there should be more...


Greetings,
Philipp
