Matt,

I looked at this and did what it says for 1 of my phones.
Still no go.

I have a mix of polycom and cisco phones at this location and
the polycom continue to work. The cisco are now having issues.
The only change that had been made is the customer changed their firewall.

All addresses remained the same just a new firewall. Polycom works cisco 
is not registering.

Any thoughts?

Jerry




Hi Jerry, 

Hmm. We had to replace our router with one that supported SIP ALG (we went
cisco). However, since you mention all the phones are in the LAN this
shouldn't make a difference. 

Does the problem go away if you go back to the old firewall?

Thanks,
Matt
