 +===== Article Now Archived ===== 
 +This article appears to no longer be valid. Hamshack Hotline engineering upgrades seem to have provided a solution to this issue.
  
 +Around a year ago T-Mobile starting blocking UDP port 5060 and held it in reserve for their own use. This meant T-Mobile users couldn't get on the HH service. So, we suggested users either us a VPN, or change port numbers. 
 +
 +__Then all the other carriers started doing the same "UDP 5060" port reserving__. 
 +
 +So, we added TCP connections as an option. Now all new provisioning we do is with TCP set as the transport.
 +
 +This means we can remove the wiki warning regarding Charter / Spectrum users, as our new TCP method is by-passing their UDP block.

 +=== (Archived) Charter / Spectrum ISP Warning ===
 +
 +Hamshack Hotline has been receiving more and more service tickets from <font inherit/inherit;;#ffa500;inherit>Charter / Spectrum</font> customers, for intermittent drop-outs, where your phone will stop registering and not work for a few minutes, then start working again. This cycle repeats through out the day.
 +
 +If <font inherit/inherit;;#ffa500;inherit>Charter / Spectrum</font> is your ISP, they have recently begun blocking VOIP port UDP <font inherit/inherit;;#ffa500;inherit>5060</font>, the standard port for VOIP phones. (They only want it used with "Their" VOIP service")
 +
 +One fix we've had success with is to manually change your HH default VOIP port from UDP <font inherit/inherit;;#ffa500;inherit>5060</font> to UDP <font inherit/inherit;;#ffa500;inherit>5065</font>.
 +
 +Below are the instructions for a Cisco Model phone. (Your instructions may be slightly different for a non Cisco phone)
 +
 +To do this, go into your phones GUI. You'll also need to be in the "<font inherit/inherit;;#ffa500;inherit>Admin - - Advanced</font>" menu.
 +
 +Go to the "<font inherit/inherit;;#ffa500;inherit>Ext 1</font>" tab (We're assuming you have your HH ext on line button #1 of the phone)
 +
 +Scroll down to "<font inherit/inherit;;#ffa500;inherit>SIP Settings</font>". On the "<font inherit/inherit;;#ffa500;inherit>SIP Port</font>" setting, change it from <font inherit/inherit;;#ffa500;inherit>5060</font> to a new value of <font inherit/inherit;;#ffa500;inherit>5065</font>.
 +
 +Scroll to the bottom and click "<font inherit/inherit;;#ffa500;inherit>Submit all changes</font>".
 +
 +Wait for phone to re-boot.
