[Spce-user] Resending - REFER / REINVITE

How can I get the cisco to use REINVITE and not REFER? I've looked at the
cisco docs and can't find a way to disable this in config.  Surely when the
INVITE comes from the SPCE to the cisco handset (a SPA502 7.4.9c) without
REFER in the Allow: header it shouldn't use it?

This is the Allow header from the SPCE to the handset:

 

Allow: INVITE,BYE,ACK,OPTIONS,CANCEL,SUBSCRIBE,NOTIFY,INFO,PRACK,UPDATE'

Supported: 100rel,timer'

 

Regards

 

John
