Hello, I would like to know how Asterisk deal in this case: Assume I have a Main Asterisk Server located in UK, and another box that have PSTN interfaces located in China, now the purpose is to FW calls through PSTN. Assuming I have a client who is calling from Japan to my main switch in UK and he is calling China, (japan have latency around 500ms to UK and 100ms to China), how asterisk will deal with this call?? Will his latency be JAPN->UK + UK->China (around 1000ms !) or only from Japan to China??? Please let me know. Thanks. -------------- next part -------------- An HTML attachment was scrubbed...

This is calling re-INVITE, and can be turned on on asterisk. For other protocols there are similar features. I think your latency figures are a little bit exaggerated if you speak about the network latency. I am in Spain and my latency to China at my home ADSL is arround 80ms for mainland. 250ms to Tokio tough. Regards -- Iv?n Stepaniuk Alba Fot?nica S.L. www.albafotonica.com

Be sure not to run into trouble for running inlicenced ip-telephony in China, so the government can't (as easily) intercept your calls.

[asterisk-users] Asterisk Integration with RDP Property Management Software?
Hi, Does anyone know of a module that integrates Asterisk with the Resort Data Processing property management software? I have a potential VOIP client but they need PBX integrated with the RDP software for call billing. Thanks, David Wathen Wathen Consulting Senior Consultant Cell: 303-435-1107 Office: 720-222-1176 Email: david at wathenconsulting.com
