Hi Aamir,

I think you should be able to get this working.

FYI - CME doesn't officially support third party SIP phones.

This is the minimum require configuration for SIP CME if you want to try it:

voice service voip

sip

registrar server

voice register global

mode cme

source-address 1.1.1.1 port 5060

max-dn X

max-pool X

voice register dn 1

number 1000

voice register pool 1

id mac XXXX.XXXX.XXXX

type ! If it's 3rd party, omit this

number 1 dn 1

username X password X ! Required if IP phone's address is on different subnet than SIP CME source address

Most SIP phones will register with SIP CME, yes. It just isn't officially supported, but the CME should be fully RFC compliant. This will allow other types of phones to register.

hth,

Hi

Thanks for your reply just getting confused in source-address can it be any IP or the ip of the router. for eg i am using IP 192.1.20.1

so the source address will be 192.1.20.1 port 5060

Thanks

I managed to configure and connect the sip phone but there is a problem the call is dropping after 18 sec.

Check your firewalls - sometimes they'll drop the traffic.
