Chuck, Always difficulty with pfSense and SIP. The following I copied from the pfSense [ http://www.pfsense.org/index.php?option=com_content&task=view&id=40&Itemid=43] website.
"SIP Limitation - By default, all TCP and UDP traffic other than SIP and IPsec gets the source port rewritten. More information on this can be found in the static port documentation<http://doc.pfsense.org/index.php/Static_Port>. Because this source port rewriting is how pf tracks which internal IP made the connection to the given external server, and most all SIP traffic uses the same source port, only one SIP device can connect simultaneously to a*single server on the Internet *. Unless your SIP devices can operate with source port rewriting (most can't), you cannot use multiple phones with a single outside server without using a dedicated public IP per device" -- If my Asterisk server on the internet (Hosted outside the network). Then my phones on the local network one phone only able to connect at a time to the Asterisk.
