[SIPForum-discussion] Problem with conesction to remote sites.

[Rudy Rawlins]

Willy:

Your phone behind the NAT needs special treatment to work. You have to configure your VoIP server to recognize the NAT phone, I.e., that their registered IP address is unreachable.

Good day all,

 

I am sure that this is one of the problems that you have discussed before, but I am unable to search the archives of this forum. Also I am not sure if this Problem is good placed in this forum. So if it is misplaced, can someone help me of list please.

 

 

Situation:

I Have a VOIP telephone switch behind a Cisco pix 501firewall. Then connection to the internet is Via an IAD to a 1Mb  DSL  line. We have fixed IP addresses. 

I have 2 VOIP telephones on a remote location behind a NAT router and 1 VOIP telephone on an other location direct on internet.

 

Problem:

All the telephones do always register, but sound is only heard once in a wile on the telephones behind the router. The telephone that is connected direct to internet 

works fine.

 

Questions:

What could be the course of this problem,    

How can I solve this problem?

 

Thank for helping me,

Willy
