Jabber on iPhone IOS registered as SIP phone on CME, outbound call fails.

NOTE:
Even though we have g711ulaw configured under voice register pool for jabber client, in the INVITE message from Jabber client we always see g729 codec.

NOTE: Make sure we do "create profile" under "voice register global" and restart the jabber application, every time a change is made under "voice register pool"
====Fix====
-Disable low bandwidth option on Jabber on iPhone IOS
-We can keep low bandwidth option on jabber, but then g729 codec as to be there under voice register pool or voice-class codec applied on the voice register pool. So all the calls from/to Jabber client will be on g729 codec.
