If you are and iPhone aficionado, you absolutely want your iPhone to work on your ShoreTel IPBX! I recently downloaded VeNetCorps SipPhone from the iPhone App store! There are several SIP phone apps at the store, but most have a pre-programmed domain name for the sip registration proxy server. If you want to use your own SIP proxy there was no easy way to change the IP address so you had to hack your DNS to get it to point to the ShoreTel SIP proxy. Also you need at least iPhone firmware 2.2 as previous versions had WiFi connectivity challenges that negatively impacted the potential for using a SIP soft phone.
After the iPhone WiFi acquired an IP address, if you attempted to ping the address you would see latency in excess of 300ms. With version 2.2 this issue has all but become unnoticeable. As with any SIP extension setup on ShoreTel, you need to assign sip extension proxy resources on a ShoreGear switch. In the sites section of the ShoreWare Director, Make sure you assign a virtual IP address. This is the address that you use for your iPhone SIPphone "domain" when setting up. Of course, you will need a Manager user setup with a SIP phone password ShoreWare defined in each section of the user.
Clearly, the assumption is that you have a WAP, make that your iPhone connection. The fact that the wireless network can route ShoreTel! Once ShoreTel SIP users, virtual IP address and proxyresources are configured it is time to configure your iPhone Sip Phone! After you down load the application and tap to activate the application you will get a screen that lists the options: Dialer, Recent, Contacts, Accounts and Settings. Hit the Accounts tab and you will then EDIT a new SIP account.
To get this app to work on ShoreTel you need to enter only three values. First you need to enter the domain name, we have previously defined in the ShoreTel Director as the Virtual IP Database. The user name and password are specified in individual user ShoreTel. Hit the tab end and the phone should register and you can make calls and received by ShoreTel. I have a video clip you can see that it works will include acute! The video shows that enter the user name, but if you want to make the iPhone a kind of extension ShoreTel, the extension user. This was just a fun project and latency oniPhone WiFi is always a challenge for the SIP phone to be used again. I suspect that the version 3.0 of the iPhone will solve this little problem, but it was a blast to try! Have fun!
