Hi,
We have a few VVX411 phones out in the wild, they are getting ghost calls so I've had a poke about & found the 2 lines:
voIpProt.SIP.requestValidation.1.method="source" voIpProt.SIP.requestValidation.1.request="INVITE"
When I put these into the config the phones stop accepting calls....
In the log, i've turned on debug for SIP & can see this:
0722091449|sip |1|00|Try to do source validation 0722091449|sip |1|00|CCallBase::IsTrusted : NAPTR lookup for '<CHANGED>.nebulaip.com' OK 0722091449|sip |1|00|CCallBase::IsTrusted : NAPTR lookup for '<CHANGED>.nebulaip.com' OK 0722091449|sip |3|00|Challenge failed !!
It then appears to send:
0722091449|sipp |0|00| SIP/2.0 400 Bad Request
If I take those 2 lines out it starts to work again.... (but so do the ghost calls.)
the part where it says <CHANGED>.nebulaip.com is the server that it connects to so i'm not sure why it's not working...
I have come across an extra line voIpProt.SIP.requestValidation.digest.realm="PolycomSPIP"
I'm not sure what that does though?
Can anyone shed any light on the matter?
Thanks!
Garry
