openh323v1.17.1
pwlibv1.9.0

all the installations were successful

the thing is when i try make calls using the oh323 driver by creating a oh323 channel the following happens

Executing Dial(“SIP/63201-ed8f”, “OH323/63101@10.238.115.223”) in new stack

-- H.323 call to 63101@10.238.115.223 with codec(s) alaw ulaw gsm g723 g729
