Trouble Configuring Tropo

cssindhu's picture


I have configured VoIP Drupal to use Tropo by the book. when i dial the number i get a bust tone... Tropo logs says 301 redirect error... the support guy told me the error is in

Declaration of Call::__construct() must be compatible with BaseClass::__construct()
in /public_html/sites/all/modules/voipdrupal/modules/voiptropo/tropo_webapi/tropo.class.php
on line 845

FYI everything was working fine just few months back... has anything changed?

Thank you... Yes I did change
