How can I use my Cisco acquired Codian product with Voiptalk?
Voiptalk allows users to register and make phone calls to other users anywhere in the world using the SIP protocol. Cisco TelePresence MCU, IP VCRs and IP GW products can register and make calls using Voiptalk by following these steps:
- Obtain a Voiptalk login* for your Cisco acquired Codian unit from www.voiptalk.org/products/signup. This requires an email address to which Voiptalk will send an ID and password.
- Go to Settings > SIP and enter the details below.
In the SIP section:
- Set SIP registrar usage to Enabled
- For SIP registrar domain enter voiptalk.org
- For SIP registrar type select Standard SIP
- For Username enter <voiptalk id from introductory email>
- For Password enter <voiptalk password from introductory email>
- Set Allow numeric id registration for conferences to Enabled if you want callers to dial straight into a conference using a numeric id. Setting a numeric id is explained in step 13 below.
In the SIP call settings section:
- For SIP proxy address enter nat.voiptalk.org:5065
- Leave Maximum bit rate from OCS/LCS clients unchanged.
- For Outgoing transport select UDP.
- Leave Use local certificate for outgoing connections and registrations unchecked.
- Click Apply changes.
The Cisco acquired Codian product will register to Voiptalk. You can now call between this and other Voiptalk accounts in either direction by dialing the Voiptalk ID.
Note: Any firewalls between the endpoint and Cisco acquired Codian product must be SIP aware and have the relevant ports open to allow the call messages and media.
- If you want callers to dial straight into a conference, add a conference on the MCU with the number of the Voiptalk ID. Alternatively, go to Settings > Conference and for Incoming calls to unknown number select Create new ad hoc conference. This will create a new conference with that number each time a user dials in. Note that is a device-wide setting. (Setting that field to Default auto attendant will connect people to the main auto attendant so they can navigate to different conferences.)
- For IP GW users, you can dial PSTN numbers through Voiptalk by setting up a dial plan rule which routes the called number to SIP Registrar.
