I have an issue with a CME 7.0 on a 2821 platform. This customer is currently using E1 PRI to dial outside but he would like to try Sip call from local provider. So I did the configuration of the SIP Trunk. My gateway is registered and incoming calls to ephone ( sccp ) are working.
However I noticed a strange behaviour with outgoing call.
Here is what happen:
Cisco 7941 SCCP phone with extension "91" (registered to CME) place a call over the SIP trunk.
If I make a debug ccsip message, I can see the first packet sent (which is INVITE) has a completely wrong header (I believe):
Here is the first Outgoing Packet:
INVITE sip:[email protected]:5060 SIP/2.0
Via: SIP/2.0/UDP 10.10.10.254:5060;branch=z9hG4bK8E2259
From: "CCC" <sip:[email protected]>;tag=5C29C8-24F4
To: <sip:[email protected]>
Date: Thu, 09 Sep 2010 12:08:42 GMT
Call-ID: [email protected]
Allow: INVITE, OPTIONS, BYE, CANCEL, ACK, PRACK, UPDATE, REFER, SUBSCRIBE, NOTIFY, INFO, REGISTER
CSeq: 101 INVITE
Contact: <sip:[email protected]:5060>
My CME Address: 10.10.10.254
Sip Provider Address: register.XXXXXXX.com
My ephone-dn used: 91
So my question is: Why do I see at the top of the packet From: "CCC" <sip:[email protected]>
I guess I'm supposed to see From: "CCC" <sip:[email protected]>
Fyi, all me DN on CME are configured with "non-reg both" command.
Any Idea ????
