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.
Solved! Go to Solution.
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.
First thanks for reply and your suggestion.
Yes i am using SIP (X-lite) softphone in Iphone and its working well when i have wireless connection but its not working with 3G internet from SIM card.
you mean, we need to add a subscriber with CUCM additionally on DMZ..?
Have a Good Day....!!!
