Hello all,

   I have 3G internet in Iphone and i want to connect my iphone to CUCM 6 with third-party sip devices. I have not Gateway. I am using Site-to-site VPN. so iphone can ping CUCM but its not registered in CUCM.Can some one tell me how it will work or i need pstn gateway or any configuration. Because when i connect my iphone with wireless internet then its registered and working fine.

thanks

Are you using VPN connection when on the 3G network to communicate back to CUCM?

Unless you put your CUCM on DMZ or make it publically routable you need to use VPN from iPhone to access it.

Are you running some kind of SIP client on your iPhone that you would like to utilize as SIP phone registered?

My recommandation would be to upgrade your CUCM and deploy Jabber to your iPhone for best results as anything else would not be supported even if you get it to work.

HTH,
