Cisco 7942 SIP protocol not registering with Asterisk

Posted:Sun 25 of May, 2014 (09:30 UTC)
I have 4 Cisco 7942G IP Phones which i have converted from SCCP to SIP.
I am also testing using the Cisco IP Communicator 7, converted to SIP protocol, to test and having the same issue with it.

I have an Asterisk install, utilising an ldap directory for sip accounts.
When i configure the cnf.xml file with the user details, the IP Phone stays on registering and does not complete registry, i keep seeing in Asterisk CLI the following error:

[May 25 01:51:19] WARNING[2290]: chan_sip.c:30963 build_peer: Qualify is incompatible with dynamic uncached realtime.  Please either turn rtcachefriends on or turn qualify off on peer 'user'
[May 25 01:51:19] ERROR[2290]: res_config_ldap.c:1334 update_ldap: Couldn't modify 'name'='user', dn:uid=user,ou=xxxx,dc=xxxx,dc=xxxx,dc=xxxx because Invalid syntax

I can use the same username/password with MicroSIP softphone with no issues.

Any help would be much appricated.
