[sr-dev] UAC Issue

[Bernhard Suttner]

Hi,

I am using UAC to register to an outbound provider. Kamailio (3.1.0) does send the following REGISTER:

E..'A... at .=...P...P9......\1REGISTER sip:172.16.0.57 SIP/2.0
Via: SIP/2.0/UDP 172.16.0.130;branch=z9hG4bKa69c.50411006.0
To: sip:SIP001 at 172.16.0.57
From: sip:SIP001 at 172.16.0.57;tag=533cb9e91f4b999cf76861cbb9ed54ed-c10d
CSeq: 10 REGISTER
Call-ID: 7bad8cfd-13535 at 127.0.0.1
Content-Length: 0
User-Agent: kamailio (3.1.0 (i386/linux))
Contact: <sip:@172.16.0.130>
Expires: 600
Authorization: Digest username="SIP001", realm="asterisk", nonce="1be9f4f2", uri="sip:172.16.0.57", response="e46d865eb495e170fdef058b857d7b76", algorithm=MD5

I am not really 100% sure, but I think the Contact address is not valid. Within the database I have only set the host part. I think the Contact should be the following then:
 Contact: <sip:172.16.0.130)

(without the @).

In addition, I think the Call-ID could be better. I know, that it is valid to set it like that, but the IP Address 127.0.0.1 could be misunderstood somewhere.

Best regards,
Bernhard Suttner
