8800/7800 3PCC sip.instance >> GRUU support?

Hi,

 

how can I get my 8841, 7821 and 6825 (DECT-VoIP) 3PCC phones to add the "sip.instance" parameter in the SIP messages?

My phones do not send "gruu" in the Supported header, nor add the "instance" in the Contact header.

 

Here is a sample log from a SNOM phone, jutst to understand, what I need...

REGISTER sip:pbx SIP/2.0
Via: SIP/2.0/UDP phoneIP:5060;branch=z9hG4bK-b12m9r9qvqh3;rport
From: "Ext 905" <sip:905@pbx>;tag=3xq79cc9he
To: "Ext 905" <sip:905@pbx>
Call-ID: 3c268399b04e-b2e3tpb6b9eb
CSeq: 12 REGISTER
Max-Forwards: 70
Contact: <sip:905@phoneIP:5060>;reg-id=1;q=1.0;+sip.instance="
<urn:uuid:e960df68-8f5d-4fec-aab4-1678c7bd76a0>"
User-Agent: snom370/7.3.14
Supported: gruu
Allow-Events: dialog
X-Real-IP: phoneIP

Exact same problem here.

Enterprise unit is sending the sip.instance but mpp phone does not.

Please retry after setting Dialog SDP Enable to Yes

Voice->SIP->SIP Parameters->Dialog SDP Enable->Yes

 

Thanks.
