Below are instructions on configuring a SIP client to work with SDF's VOIP service. Please see the SDF VoIP tutorial for more information.
Linphone may be installed by searching for “Linphone” in the App Store or by clicking here to open the App Store page on your iOS device.
Once you have installed the application, open the general settings application on your iOS device. There are no settings within the app itself. In the general settings application, scroll down until you find an entry for Linphone. Tap it to open Linphone's settings
The following settings need to be filled:
Download and install ekiga. During the initial run, a wizard will appear. Cancel out of the wizard and manually add an account with the steps below. More information can also be found on ekiga's documentation site.
The Grandstream GXP2000 is an office SIP phone. It is fairly straightforward to setup via the phone's web interface. Below is a screenshot with highlighted options needed for it to register and work properly with SDF's VOIP system. Here are some items to note:
Grandstream HT801/HT802 are Analog Telephone Adapters which support analog phones, including older rotary dial models. Newer firmware versions allow pulse dial and high powered ringing. The HT802 supports two lines.
The Grandstream Handytone 286 is a simple analog telephone adapter. It can allow you to use any analog phone with the SDF VOIP service. It can be configured using the built-in web interface or through voice prompts by dialing
*** on an analog phone.
You should also forward UDP port 5060 to the Handytone's IP address through your router. It may be a good idea to set the Handytone to a static IP address, which can be done on the Basic Settings tab. Don't forget when doing this to add all the relevant fields, including a proper DNS server, else the Handytone won't be able to resolve the sip.sdf.org address.
Android 2.3 and up seems to have a built-in SIP client. The screenshots below are from Android 4.3. This is tested with wifi data, and 3G/HSPA on tmo. Some carriers or specific android versions may disable SIP calling over cellular data.
|1||From the Android home screen, tap the phone icon to go to the dialpad.|
|2||Tap the settings icon on the lower right button.|
|3||Select the Settings option.|
|4||Optionally, select the “Use Internet calling” option to select when to use SIP calling, and when to use the regular calling function. In this case, I select “Only for Internet calls” only for SIP calls. (See contacts discussion below.)|
|5||Select Accounts to create the SIP account.|
|6||Optionally, select “Receive incoming calls” if you want to receive SIP calls on this phone.|
|7||Select the “Add Account” option near the bottom.|
|8||On the next screen, tap Username and enter only the extension number. Tap password and enter your password. Tap Server and enter sip.sdf.org. Optionally, select “Set as primary account.” This option does not seem to be necessary to make an outbound call. Maybe this is only used when multiple SIP accounts are configured? Tap save to save the settings. Now things should be ready for a test call.|
When making a call from the dialpad, there does not seem to be a way to enter the @ sign. If “Use Internet calling” is set to “For all calls”, then this is not an issue: just type the extension number and tap call..
Another way to make SIP calls is to add the SIP number (email@example.com) into the contacts, and select the number from the address book. Android seems to detect the @ sign and automatically switch to internet calls regardless of what the “internet calling” setting and the “Set as primary account” setting is set to.
Finally, Google Contacts also has the option of labeling a number as “Internet call” which will trigger SIP calling as well.
