CME 8.5 and Iphone

epasqualotto · ‎01-10-2011

Hi all, I'm trying to use my Iphone as extensions of my CME

I've tryed both CounterPath Bria and Linphone with this configuration:

voice register global
mode cme
source-address 192.168.10.254 port 5060
max-dn 20
max-pool 10
authenticate register
authenticate realm cme
tftp-path flash:
file text
create profile sync 0372431455915402

!
voice register dn 1
number 1207
allow watch
name Enrico
no-reg
label Enrico
!

voice register pool 1
id mac 0000.0000.0000
number 1 dn 1
presence call-list
dtmf-relay rtp-nte
username 1207 password XXXX
codec g711ulaw
!

The SIP client is registered with CME and these are the results:

Linphone: two way audio, outgoing calls OK, incoming calls FAIL

Bria: one way audio, outgoing calls OK, incoming calls OK

Can someone share his experience with Iphone, how can I use it with my CME in SIP mode?

Thanks

Enrico

This is what I see in the debug when the incoming calls fail:

Then something is wrong with the registration, because phone is registered as .86, CME sends invite to a different IP, from which receives no answer.

epasqualotto · ‎01-10-2011

No because I take the debug from another router with different IP.

This is the correct debug:

1007 is my SCCP phone

1207 is my SIP client

192.168.99.1 is the router IP

192.168.99.86 is the SIP client IP

Thanks

The you have to find why the iphone does not respond to the Invite message.

epasqualotto · ‎01-11-2011

Finally I have my Bria client on Iphone registered and woriking with CME 8.5, the problem is the default NAT configuration so the client present himself with the public IP. In the "advanced setting" menu the NAT configuration MUST be set to "server managed" and this solve the problem.

Enrico, had you mentioned you were using NAT it would have been easier to suggest a solution
