With TrueConf Server you can make calls to SIP and H.323 devices. Read this article to know how to make a call from Android client app to SIP/H.323 endpoint.

You can call SIP users from your Android device in four different ways:

  • #sip:Call_ID@Server_name, where Call_ID is a SIP user, Server_name is a host name or SIP server IP-address (#sip:james78@sipnet.ru);
  • #sip:Call_ID, the call is directed to the Call_ID on the server, set in the VoIP Server /SIP Proxy section of SIP Gateway tab (#sip:james78);
  • #sip:@IP, call using SIP endpoint IP address (#sip:@192.168.0.7);
  • #sip:@hostname, call using SIP endpoint DNS name.

Let’s make a SIP call using the following format: #sip:Call_ID@Server_name. Creating your own conference is easy!

How to call H.323 terminal

To call directly to H.323 endpoint via IP, the following combination is used: #h323:@IP, where IP is the target endpoint address.

To make an H.323 Terminal call with external H.323 Gatekeeper, use the following combination: h323:terminal_id, where terminal_id is the target endpoint identifier, or combination #h323:\e\terminal_e164, if the identifier is in E.164 format. To make SIP users visible by the H.323 Gatekeeper or MCU, TrueConf Server must be pre-registered in both examples above.
