Problem Summary: Can not dial extensions phones connected via LinkSys
SPA-2102 or LinkSys SPA-3102

First: I apologize in advance if I missed the answer to this somewhere, but
I haven't been able to find anything anywhere that has worked.  Also, I
tried to post properly and give enough information without going overboard,
I am sorry if it is still too much (or too little).


Configuration:
. Fresh install of Fedora 8 and sipXecs 4.0
. sipXconfig (4.0.0-015321 2009-04-28T13:02:58 ecs-fc8)
. Latest firmware on both LinkSys SPA adapters.

. SPA-3102
Software Version: 5.1.10(GW)
Hardware Version: 1.4.5(a)
Connections:
Network: Internal private dedicated VoIP network
PSTN Line: Local POTS Line (Ext. 214)
Line 1: Southwestern Bell corded phone (Ext. 215)

. SPA-2102
Software Version: 5.2.5
Hardware Version: 1.3.5(a)
Connections:
Network: Internal private dedicated VoIP network
Line 1: Phillips CD 440 DECT 6.0 Cordless (Ext. 220)
Line 2: GE Slimline corded phone (Ext. 221)

. Polycom SoundPoint 320

. sipXecs
Users setup for each extension, User ID 215, User ID 220, etc.
Phones / adapters setup and assigned to users
All phones, adapters, devices, etc. are registered and showing under
"Diagnostics > Registrations", no issues or errors.

. Me:  Experienced in computers (more Windows based then Linux) but no
previous experience with VoIP, sip, sipXecs, etc.


Problem Details:
------------------------------------------------------------
>From Polycom (Ext. 250) I can direct dial any extension (e.g. press 215,
220, 260 etc.) and it rings straight through to the extension, including any
phone connected to either LinkSys SPA, no problems.

>From X-Lite SoftPhone (Ext. 260) I can direct dial any extension (e.g. press
215, 220, 250, etc.) and it rings straight through to the extension,
including any phone connected to either LinkSys SPA, no problems.

>From anything connected to an SPA, corded phones on Ext. 215 & 221 or the
cordless on Ext. 220, I can dial 0, 100, & 101 without any problems.  I can
dial 100 and dial an extension (e.g. press 100, wait for the attendant to
answer, and then press 250) and get transferred and it rings through to the
extension, no problems.  But, if I try to direct dial any extension (e.g.
press 220), all I get is a busy signal.

Bottom line, from the Polycom and the softphone, I can direct dial any
extension.  From any phone connected through an SPA, I can not direct dial
any extension.


Things I have noticed:
------------------------------------------------------------
. I can get out to my POTS line via the PSTN Line on the SPA-3102 from the
Polycom and the soft phone.
. Calls that fail from the SPAs show up under "Diagnostics > Call Detail
Records > Historic" with a Duration of "0 seconds" and a Status of "Failed"


Things I have tried:
------------------------------------------------------------
. User resets on the SPAs
. Factory resets on the SPAs
. Increasing the DTMF Playback level on the SPAs
. Increasing the DTMF Playback length on the SPAs
. Reduced the RTP Packet Size to 0.020, and also tried 0.010 on the SPAs
. Under the "SIP Timer Values" on the SPAs, change the following:
SIP T1: .7
Reg Max Expires: 1200
Reg Retry Intvl: 30
Reg Retry Long Intvl: 110

. Updating the firmware on the SPAs
. Reinstalling Fedora & sipXecs
. Digitmaps I have tried on the SPAs:
Original: (*xx|[3469]11|0|00|[2-9]xxxxxx|1xxx[2-9]xxxxxxS0|xxxxxxxxxxxx.)
>From the Polycom:
([2-9]11|0T|100|101|011xxx.T|9011xxx.T|1[2-9]xxxxxxxxx|91[2-9]xxxxxxxxx|9[2-
9]xxxxxx|*xx|[8]xxx|[2-7]xx)
Bare bones: (0|100|101|260|[2-7]xx|[8]xxx)
Other variations of desperation (and some others not listed):
([1-8]xxS0|9[2-9]xxxxxx|91[2-9]xx[2-9]xxxxxx|9[69]11S0)
([2-9]11S0|[8]xxx|[2-7]xx|0S0|100|101|011xxx.T|9011xxx.T|1[2-9]xxxxxxxxx|91[
2-9]xxxxxxxxx|9[2-9]xxxxxx|*xx)
(*xx|[3469]11S0|[8]xxxS0|[2-7]xxS0|0S0|00|[2-9]xxxxxx|1xxx[2-9]xxxxxxS0|xxxx
xxxxxxxx.)



Any suggestions would be greatly appreciated and thank you all very much for
your help and your time.

Cheers,
Clint
