To quickly restore a call previously established between first and second terminals (T1, T2) linked respectively to first and second call servers (SAS1, SAP2), a first call string (MG1, MCA1) is created in association with the first terminal and a first context of the call prestored in the first server. A call restoration request including a second call string reference extracted from the first context is transmitted from the first server to the second server. In the second server, a second call string (MG2, MCA2) is searched as a function of the reference included in the request. If the second string is found in association with the second terminal, a restoration of the call between the first and second terminals through a route between the first and second call strings is confirmed by the second server to the first server. |
