I am trying to connect a couple of the older xts lip-24's (3813-02) to a summit. They work perfect on the same lan with mac registered under p235. But when I go remote, they will register and even show as a lip-24 under device ip plan and show the public ip AND the lan ip of the phone itself but the phone says no response from mfim. I don't have any of the newer ip sets to try.I haven't done any remote ip sets other than the ucs mobile so I can't be sure I know what I am doing. The only difference seems to be to entery the mac under p442 instead of p235. I also tried forwarding all ports on both sides.

If someone wants to do a test with a newer one I can program your mac into my switch and see what happens. call three oh zeven 679 7785

Do you have your WAN IP programmed in PGM 102, "Firewall IP Address"?

Yes i do, the sip trunks also require it and won't work without the correct firewall ip entered in p102.

I would be surprised if this is a set issue, if they work on a lan they should work remotely. I think that this is an ip address/port forwarding issue.

Pgm 235 is the registration table for Summit Systems on the same LAN. For remote operation of ip phones clear the mac address out of 235 and enter it in pgm 442. Make sure the phones are programmed for the MPB mifm Public Wan address. You could forward the same ports as for the UCS 1720-9999

That's not always true. SIP depends on your settings in SIP CO Attributes, and also how your router is setup.

While I've never tried that model, I agree with Derrick that it "should" work from the outside if your router is set properly.

Here are the ports:

UDP 5060 = SIP Signalling Channel.

UDP 5588 = Unicast port

UDP 6254 = Multicast Port

UDP 7000-7015 = Voice Channels

UDP 7100-7115 = Voice Channels

UDP 7300-7315 = Voice Channels

UDP 10,000-10,239 = VOIU switching channels (only put this in if using virtual switching channels).

Under p442 I leave the password blank correct?
See if this looks right in the phone programming:

mode=remote
vlan- not set/can't change
dhcp = curently disabled (I tried both ways)
ppp=disabled
pw/user id for ppp I assume leave blank
device number=ext number
mfim = public ip of summit router w/above ports forwarded
Router ip = internal ip of local router on the phone lan
net mask = 255.255.255.0
phone ip = lan ip of phone

Do I need to forward any ports on the phone side router?

Normally that is correct. If you've already connected the phone to the system on the LAN, then you don't need to enter anything in 442. The system has registered the MAC of the phone.

mode=remote (Yes)
vlan- not set/can't change (Correct)
dhcp = curently disabled (Should be set to yes in most cases. This is how the phone gets the IP from the local (phone side) router.)
ppp=disabled (Correct)
pw/user id for ppp I assume leave blank (Correct)
device number=ext number (No, should be blank)
mfim = public ip of summit router w/above ports forwarded (Correct)
Router ip = internal ip of local router on the phone lan (Correct. This will be auto assigned if you use DHCP)
net mask = 255.255.255.0 (Yes, if that's your LAN configuration. Auto assigned if use DHCP.)
phone ip = lan ip of phone (Yes. Again, DHCP will take care of this.)

Do I need to forward any ports on the phone side router? (Normally no.)

SOLVED, I purchased a VIP series phone and it works perfect remotely.
Everything about the phones programs the same way but the old xts phones will only work in local mode on the same lan. I will just keep the old ones for local users and not worry about it.

Thanks for all the help!

Is there a way an admin can change this title to something more helpful like "using remote xts ip phones on a summit" in case someone runs into this problem again....

I will take care of it.
