IPO SIP Configuration

[BusinessPhoneSystems]

We have found the following vital in configuring SIP:

1) Running Stun - even if it doesnt do much but define the firewall or router.
2) Set the registration expiry to below the NAT timeout - we use 60, which creates traffic but resolved some issues.
3) Request a static nat feed for sip trunks and configure in firewalls and routers.

To experts the above may seem obvouse but we have found these to be a dark art and not always covered in the manuals.

Manuals? for SIP? HAHA! : )

If the IPO was only doing what was in, or only being set up as per manual procedures, it would not be doing much of anything. The manuals don't walk through much, and only the cookie cutter stuff as a rule. To make this puppy rock you have to take it out of the case, and break some strings.
