IP SIP Phone without proxy

Hello there,

I know this question might sound a bit stupid but...

It was my understanding that SIP agents don't necessearily need a proxy to establish a connection. In particular, I thought I can make to Cisco IP SIP phones connect to each other without additional products. However, I did not manage to do that.

I would appreciate any comments/references.

Regards,

Dobromir

Re: IP SIP Phone without proxy

Please try the following,

The outbound Proxy and the SIP Proxy should be set with the IP address of the remote Phone.

Userid and Psw should be turn off, cancel the REGISTER option exists in SIP.

In that case you will be able to do ip2ip phone calls only between the 2 IP Phones.

If you need to make many to many phone calls over IP then you at least need SIP Proxy server. Cisco has CSPS 1.3 which can be used for that task.
