A method at a telephony device comprising: sending to a web server, over an internet connection, a request to establish a telephony call with a destination telephony device, the request comprising an identifier (e.g. an application serial number of a software application at the calling party) associated with the calling telephony device; receiving, form the web server an intermediate code (e.g. a DTMF code, or a temporary telephone number or any reference that may be sent as part of a telephone call); making, in response to receipt of the intermediate code, a telephony call to a telephony call handler connected to the web server, the telephony call comprising details of the intermediate code and also comprising a telephone number of the telephony device. In various examples, a web server establishes a link between a calling party identifier and a telephone call from the calling party from which the telephone number of the calling party is observed. The web server 104 searches for and finds a link between the calling party telephone number and the calling identifier. This link is found through the intermediate code. |
