Problem with accessing Zoho CRM from office Internet

Problem with accessing Zoho CRM from office Internet

Hi Support,

We seem to be having an issue with Zoho hanging for long periods of time when accessed from our office DSL connection (1.5 Mbps).  Despite other web pages loading correctly, we have long, long, long pauses and hang times when entering data in Zoho, when opening Help windows, etc.  (note: there are no problems using Zoho CRM from remote locations).

Our office DSL provider suggested that we may have a port conflict, and would like to know which ports Zoho CRM servers use to establish connection.  Please let me know as soon as you can, we like the CRM but need it to work properly from our office location.

Thank you!
