Sip phones

[tazz29063]

I have two sip phones working off a ta908e. Everything seems to be working properly. The only issue I have is, I will get random numbers ring the sip phones. 5005,3001,1001,601,2900(shows as CID). All my DIDs are 10 Digits. How do I get theses odd numbers to stop ringing the sip phones?

It sounds like SIPvicious. If you are using Polycom phones add this to your config file

<voIpProt.SIP.requestValidation voIpProt.SIP.requestValidation.1.method="source" voIpProt.SIP.requestValidation.1.request="INVITE" />

I'm using  Grandstream gxp2140.

Can you set up accept or reject plans on a sip phone extensions?

Make sure you're on the latest firmware version and add this to your config file:

<!-- Accept Incoming SIP from Proxy Only. 0 - No, 1 - Yes. Default is 0 -->

        <P2347>1</P2347>

When set to "Yes", the SIP address of the Request URL in the incoming SIP message will be checked. If it doesn't match the SIP server address of the account, the call will be rejected. The default setting is "No".
