Hey guys,
Sorry it's taken a while for me to get back to you all. I've had to use firefox to be able to post as IE wouldn't let me comment. the box was greyed out.
Ok so I've fixed this now. I ripped out my config for the voice stuff and re added it. I was the presented with a problem where on the 2800 when I dialed 6000 which matched my dial-peer voice 2 ports of destination-patter 6... what happened was I would just get dial tone and then had to redial the number again with the dial tone present and that was passed over the E1 and it worked. The 2621 CME was no issue.
Basically on the 2821 I forgot to add my direct dial inwards to the dial peer.
I'll post my configs here in case anyone else would like to do the same as me. You don't have to have CUCME, you can still use my config sample if you have H.323 gateways between two CUCM's
Ok this is the 2821.
This is the E1
controller E1 0/0/0
clock source internal ----- It will be providing the clock
pri-group timeslots 1-31
!
controller E1 0/0/1
and this is the serial
interface Serial0/0/0:15
no ip address
encapsulation hdlc
isdn switch-type primary-qsig
isdn timer T310 120000
isdn protocol-emulate network ---- This part is important if you're connecting to another router
isdn incoming-voice voice
no cdp enable
dial-peer voice 2 pots
description To CME 2621
tone ringback alert-no-PI
preference 1
destination-pattern 6... - anything starting 6 with plus 3 digits gets routed out this E1
direct-inward-dial
port 0/0/0:15
forward-digits all ------- The part I forgot to add!
For the 2621
controller E1 1/0
pri-group timeslots 1-31
the clock source is set to line, framing is crc4 and linecode is hdm3. obviously both ends use the same linecode and framing.
