[asterisk-users] The SIP in the Mobile Phones are not able to register on asterisk

[bilal ghayyad]

I am talking about the SIP.

Now the new mobiles (Nokia, Erecson, Panasonic, iPot, ... etc) all of them support SIP capability. They are able to register to any SIP server (by giving the IP address, username and password). Fring is one of the software that can be installed on the mobile devices and can register on the SIP servers.

BUT, the new mobiles currently come with built in SIP (no need to install fring on the mobiles, as it come already with SIP client).

The problem that I am facing it: I tried to let my nokia mobile to register on Asterisk, but I am always failing, while I can register to other service provider.

I did alot of trouble shooting but did not succeed.

Is there any special thing need to do in asterisk configuration to let Nokia (or any other type) of the mobiles that has built in SIP to register on my Asterisk? What could be?

Regards
Bilal

Dear All;

I am facing a problem that all the mobile devices that support SIP and are
able to register with a lot of providers, they are not able to register on
my asterisk. What could be the reason? Any specific thing I have to do?

The used port is UDP 5060

Actually, any SIP Phone can register with my asterisk, but when I try from
the mobile devices, it does not !! (While these mobiles are able to register
with other SIP service provider).

Any help?
