[cisco-voip] problems with MLPP configuration with CME 4.0(0)

[Huertas García, Victor]

Hi all, 

I am configuring a Cisco Call Manager Express 4.0(0) (in a Cisco 2851) 
in order to register third party SIP phones. In principle we don't 
want to use "telephony-service" configuration because we want to 
perform a configuration regardless of whether the VoIP phone is Cisco 
or not. 

The thing is that now we have 2 SIP phones registered in the internal 
registrar server of CME and 2 H.323 phones which are not registered 
but there are two dial-peers mapping each of both. Calls between them 
work fine. 

However we want to enable MLPP at least on SIP devices but all the 
documentation I have read so far doesn't clarify my doubts and I am a 
bit lost and stuck with this issue. 

There is no SIP dial-peers configured but just "voice register pool" 
instead, which creates a virtual dial-peer in fact.The only command I 
have found regarding the MLPP in SIP phones is the "voice-class sip 
resource priority namespace...". However, this command only appears 
available in statically configured SIP dial-peers and not under "voice 
register pool". 

perhaps the problem is the call manager version but I don't know it. 

Any idea from any expert? Is there some workaround to do it? 

If you require configuration file, please tell me so.

Thank you very much for your attention 

Victor
