[cisco-voip] CME Remote IP Phones Across PIX VPN

Remote skinny IP Phone registration across a WAN to CME is not a "supported" feature. The recommended solution with CME is local skinny phone registration.
>From the release notes for 3.2 :
Remote skinny client control protocol (SCCP) phones connected across WAN links are subject to the following restrictions:
–Cisco TAC will not handle any voice or signaling issues for remote IP phones, unless the same issue can be replicated for LAN phones.
–E911 or emergency calls are not supported from remote IP phones.
–All calls made to and from remote IP phones must use G.711. Cisco CME does not support the ability to specify G.729 codec for remote IP phones.
–For inbound or outbound calls, remote IP phones cannot fail and go over to a PSTN connection. Remote phones must use the WAN for all calls, even if available bandwidth is not sufficient to guarantee voice quality.
–Remote IP phones do not support Network Address Translation (NAT). All Cisco CME phones must use IP addresses that are routeable to and from Cisco CME. Remote IP phones must be able to access the IP addresses that are used for all other local and remote phones.
–All PSTN access is through the central site only. PSTN termination at the remote site is not supported.
–Cisco CME does not support Call Admission Control (CAC) for remote SCCP phones, so voice quality can degrade if a WAN link is oversubscribed. High-bandwidth data applications used over a WAN can cause degradation of voice quality for remote IP phones.

Has anyone built a 4.1 server for the lab with 4.1.
I have done 3.3 and 4.0 without any trouble , but for some reason the
CallManager Install CDs (4.1.2) bomb out
during the Setup with a File not Found Error.
I also tried to run an upgrade from 3.3 to 4.1.2 using the CD with no luck.
Is there a file that needs to be copied to the server, or a special reg.
setting ?
I am going to try to bump the 3.3.x server to 4.x, then 4.1.x next.

Hello!
I have been testing a little something and I was wondering if anyone
else has seen this..
CME ver 3.2
PIX 6.3.3(132) on a 501
IP phone
|
PIX 501
|
Internet
|
2811 with CME/VPN
|
POTS lines
I have one way audio on the IP phone at the PIX location.
It does not matter how I try to call- To POTS or to other IP phones at
the 2811 site, the other end can hear me, but not the other may around.
I have good ping times (sub 50ms)
Packet size has been adjusted up and down from 1400 to 1492
The VPN works fine for other DATA.. The Circuit was monitored on both
ends, neither was even approaching 30% capacity
I have check the VPN access-list and it all seems fine Traffic is
flowing for all the correct IP addresses.
Thanks,
Jim

Hi Marton,
Yeah but I'm little bit confusion because as stated here: http://www.cisco.com/en/US/partner/tech/tk652/tk653/technologies_tech_note09186a0080387544.shtml
the NM-HDV2 has "enhanced time division multiplexing (TDM) capabilities" which allow to switch
audio and data bit stream between ports on the same module. The ISDN signalization is supported
here. So I wonder since the NM-HDV2 can switch ISDN data bitstrem maybe it can terminate ISDN data too.

Hi group,
how can I decode Facility info from "debug isdn q931" received form qsig trunk? The message is like this:
*Mar 4 21:11:42.492: ISDN Se0/0:15 Q931: RX <- ALERTING pd = 8 callref = 0x8004
Facility i = 0x91AA068001008201008B0100A11402010C06042B0C09018009564552534F20313032
Shift to Codeset 5
Codeset 5 IE 0x32 i = 0x81
I would like to know does it carry dial reason (it should be Fwd (NoReply)) and original number? Any tools or documentation available on this subject?
Thanks,
Ivan

Question regarding Web attendant. Is webattendant supported in call
manager version 4 xxx. I searched Cisco's web site and found only
references to documents explaining web attendant on call manager 3.0,
3.1 and even 2.4.
I also looked at our own call manager 4 admin interface and could not
find the area to configure web attendant.
