We have a small call center with 20 older SIP-T20P phones. For agent's dial out we are utilizing the Action URI interface of phones and initiate calls with in this format:

http://[Login]:[Pass]@[IP_Address]/cgi-bin/ConfigManApp.com?number=xxxxxxxxxx

And everything works just fine.

Recently our supplier said they don't have any more SIP-T20 and it's replaced by newer SIP-T21

Our problem is that our command to initiate the calls is not working anymore in new ones (though when we try to call for first time its asking for permission for first time on screen of SIP-T21 but nothing happens after granting the permission and also on all next attempts)

All that happens in browser it changes our url format from what I wrote in top to:

http://[IP_Address]/servlet?number=xxxxxxxxxxx

but in practice nothing happens on phone.

Kindly advice if we need to change something to make it work.

versions are:

Firmware Version 34.71.0.70
Hardware Version 34.1.0.0.0.0.0

Hi msx,

Sorry for the late reply.
Please refer to "ACTION URI" in admin guide of T2X-V72. This action URI syntax is the same as V71.

You can refer to more details about T21P.

Dear support,

thank you for your answer. How ever it's not clear from those documents if I'm doing something wrong. Can you please clarify these 2 points:

1. The fact that this format (http://[Login]:[Pass]@[IP_Address]/cgi-bin/ConfigManApp.com?number=xxxxxxxxxx) is not working anymore is true ?

2. Can I have an example of the URI including login/pass to call to xxxxxxxxx number ?

Thank you very much for your time and support

Hi msx,

Please test below syntax.

If you want to place a call to xxx from SIP URI y .

is the outgoing_uri=y part mandatory ? I don't have any idea what it should be as I want the ip phone with given IP address to dial out through my dahdi channel ( it does so with my config when dialing 9xxxxxxxxx ).

As an example:

my phone IP: 10.1.1.10
My Asterisk: 10.1.1.1
My phone extension: 100
login of phone: login
Pass of phone: pass
Number to Dial: 99999999

is this url correct:

?!

it simply does not work for me. absolutely no reaction on phone.

Thank you again for your help and support,

You should be able to leave outgoing off and have it use the default line.

I tried this:

In browser the url changed to:


on Phone for first time it's asking if remote control is allowed. after confirming absolutely nothing is happening on phone and no number dialed. For any consequent attempt, simply nothing happens.

I feel that I have to start searching for old SIP-T20 phones globally

How about going into remote control and ensure what IP Addresses are set? I just put any, which is a bit of a risk, but I am ok with it.
You would want to put the desktop computer, and the phone server.
The fact that he phone asked if remote control is ok means that it wants to do something.

I have any also. I tried all variation and the problem doesn't seem to be the list of ip addresses
