UC500 issue - sip phones and SIP trunk

IdontNeedNick · ‎02-23-2012

Hi,

I have a problem with SIP phones on UC500.

UC500 has a SIP trunk and when I try to make a call using a sip phone that's not working.

If I use scpc phone everything is OK.

I tried to bind interface on voice service voip for sip, to setup outgoing proxy ,... but I was not succesfull.

I found similar issues on this forum but without solution:

Thanks,

O

Router is configured to accept incoming call setups from all sources ip adds :

voice service voip

ip address trusted list

ipv4 0.0.0.0 0.0.0.0

Thanks Adam...
