Hi all , Need kind help of yours.I have following setup configured (CISCO router 29XX series)
Nortel PBX(rls5.5)---E1-->CISCO Router----->CISCO Router(FXO/FXX Port)--- Analog Tel Set
i am having problem of dropping call exactly after 2 minutes and 45 second. Analog set located at remote site use 9 to access PSTN trunk installed at Nortel PBX and then it dials out..These calls are dropping after 2 min. 45 seconds...I checked E1 route TFD it is disable(set to 0).
The CISCO logs capture shows following error
Cause No. 102 - recovery on timer expiry.
This cause indicates that a procedure has been initiated by the expiration of a timer in association with error handling procedures.
What it means:
This is seen in situations where ACO (Alternate Call Offering) is being used. With this type of call pre-emption, the Telco switch operates a timer. For example, when an analog call is placed to a Netopia router that has two B Data Channels in place, the router relinquishes the second channel, but if it doesn't happen in the time allotted by the switch programming, the call will not ring through and will be discarded by the switch.
ISDN Serial0/2/0:15 Timers (dsl 0) Switchtype = primary-qsig
ISDN Layer 2 values
K = 7 outstanding I-frames
N200 = 3 max number of retransmits
T200 = 1.000 seconds
T203 = 10.000 seconds
ISDN Layer 3 values
T302 = 15.000 seconds
T301 = 300.000 seconds
T303 = 6.000 seconds
T304 = 120.000 seconds
T305 = 30.000 seconds
T306 = 30.000 seconds
T307 = 180.000 seconds
T308 = 6.000 seconds
T309 Disabled
T310 = 120.000 seconds
T313 = 6.000 seconds
T314 = 6.000 seconds
T316 = 120.000 seconds
T318 = 4.000 seconds
T319 = 4.000 seconds
T322 = 4.000 seconds
T3OOS = 5.000 seconds
Please guide how can i resolve this problem? Further i cannot get dial tone (after 9) at analog set connected with CISCO router analog port...DLTN is yes at nortel PBX.
Regards
