Call from SCCP Phone to SIP--not working

Hi

Well actually i am testing a scenario in my lab, where i am using two cme routers. One configured as SIP gateway and other as an H323 gateway.

On the H323 router i only have configured SCCP phones but on other one the just the SIP phone.

I can make calls from SIP phone to SCCP but cant make from SCCP to SIP. Any suggestions would be highly appreciated.

exten of SIP phone is 5001 and for SCCP it is 3001

[P.S]have respected voip dial-peers created and voip service voip command configured with sip to h323 and vice versa

--On h323 gateway;

voice service voip
allow-connections h323 to sip
allow-connections sip to h323

ephone-dn  3
number 3001
label first_3001

Re: Call from SCCP Phone to SIP--not working

After a long digging into incoming and outgoing dial-peers..how they actually works ...I finally got it all working...yeaaah.

I actually was missing the right codecs   Now the below configs works just perfect . Now i do have calls from both ends.

SIP

dial-peer voice 30 voip     ----- thats an outgoing dial peer
destination-pattern 3...
session target ipv4:172.16.1.1
codec g711ulaw

dial-peer voice 40001 voip --- the implicit dial-peer created for incoming calls
destination-pattern 5001
session target ipv4:192.168.2.10:58855
session protocol sipv2
codec  g711ulaw bytes 160

H323

dial-peer voice 50 voip   -----   thats an outgoing dial peer
destination-pattern 5...
session protocol sipv2
session target ipv4:172.16.1.2
dtmf-relay rtp-nte
codec g711ulaw
