Forward DID to SIP trunk

[anoop401]

Hi,
From the tcpdump traces, what I understand the dialed number (My cell no for example) is considered as an SIP extension in the OXE, actually this call should go out to the Telco provider.
Im attaching a snippet (tcp dump).

10.40.13.252 - Asterisk
10.41.12.203 - OXE
813035xxxx - Cell no (10 digit)

I need to dial "0" from my OXE, the PRI connection gets through then cell number with prefix "0" , for normal calling (Call from OXE extension).
I need this from Asterisk.

regards
anoop

If you whant to send 0813035xxxx from SIP to PRI.
The most simple way:
- send 00813035xxxx from Asterisk (duble 0 in the begining - I think 0 - seize prefix in OXE)
- in SIP TG manage Transcoding= false (or use NPD with DID translator in transparent mode without rules)
- check COS/Connection COS 5 (1 in position 5).
- check Entity/ discriminator selector (in SIP TG Entity shall be used the same discriminator for ISDN TG like in user Entity) or use in SIP TG the same Entity like for OXE users

OXE will receive 00813035xxxx
Without transcoding number will be used as is 0 prefix for ISDN TG (I hope) and numer 0813035xxxx will be send via ISDN TG.

hi haroun
our site faraway ,and internet issue....discuss with site optr...calling no and called no are displayed in t3 traces...in both nodes...Let me know if you have any tips...thanks

[haroun]

external callback translator managed on node 2?
how users on node §2 are called from node 1?

[sadi_seemi]

user call from node 1 to node 2 through prefix plan= routing no...and prefix plan= network no.
second (external callback translator managed on node 2?) Does this not apply to outgoing calls?(reverse dialing)

[haroun]
