Hi,
I'm experiencing an interdigit timing problem with incoming calls after a configuration change.
The environment: ISDN is going into a H323 gateway, that send the calls to a CUCM 8.6
the original configuration on the H323 gateway was
voice translation-rule 1
rule 1 /^\([1-9]\)/ /0\1/ type subscriber Subscriber
rule 2 /^\([1-9]\)/ /00\1/ type national national
rule 3 /^\([1-9]\)/ /000\1/ type international international
voice translation-profile PSTN-in
translate calling 1
...
controller E1 0/1/0
pri-group timeslots 1-31
...
interface Serial0/1/0:15
no ip address
encapsulation hdlc
isdn switch-type primary-net5
isdn overlap-receiving
isdn incoming-voice voice
...
voice-port 0/1/0:15
translation-profile incoming PSTN-in
bearer-cap 3100Hz
dial-peer voice 200 pots
description ** Inbound from PSTN **
incoming called-number 555
direct-inward-dial
port 0/1/0:15
dial-peer voice 300 voip
description ** Outbound to CUCM **
preference 1
destination-pattern 555T
session target ipv4:10.10.10.10
dtmf-relay h245-alphanumeric
no vad
Everything worked, but I wasn't happy with the 555T Dialpeer so I put another translation on the voice-port
voice translation-rule 2
rule 1 /555.$/ /555100/
rule 2 /555..$)/ /555100/
rule 3 /555...$/ /\1/
voice translation-profile PSTN-in
translate calling 1
translate called 2
(Same translation was done on CUCM before)
and I reconfigured the Dialpeer to CUCM
dial-peer voice 300 voip
description ** Outbound to CUCM **
preference 1
destination-pattern 555...$
session target ipv4:10.10.10.10
dtmf-relay h245-alphanumeric
no vad
In testing everything worked fine, but in the real environment sometimes a call eg. 555123 seems to arrive only as 5551 or 55512 on the Voiceport and is translated to 555100. I think there must be an interdigit timing problem, but I do not understand why it had worked before.
I will have to change a parameter on voice port and I first thought of "timeouts interdigit" or "timing interdigit" but they seem do be for outside direction only. I know, I can apply the translation to the inbound PSTN dialpeer too, but I want to keep it on the voiceport.
Has anyone a hint for the correct solution - thanks.
