Nokia phones running VoIP Settings version 3.x CUCM 6

Hi!

Is there any way to get Nokia phones running VoIP Settings version 3.x to work with Cisco Callmanager CUCM 6?

Since Nokia changed their SIP information it now writes a randomly translated username in the contact URI, i.e. aweofj293j2c0239jdwiofje0@nataddress instead of username@nataddress, which it did prior to version 3.x.

Incoming calls works fine, however for outgoing calls there´s only one way audio. Audio works from sip to pstn, but not from pstn to sip.

CUCM 7.x supports this.

This is a big issue with customers running CUCM version 6.x. It´s difficult to justify an upgrade to version 7.x just to get support for newer Nokia phones.

Is there any good third-party SIP client out there, that doesn´t require a logon to a different sip-provider, it doesn´t have to be free.

Any help appreciated.

Regards Marenl01
