[Asterisk-Users] Voicemail, Cisco and H.323 problems
Hello.
I have a Cisco IP Phone 7940 connected to Cisco CallManager.
I have a Cisco 2600 Router running H.323 Gatekeeper
I have Asterisk server running OpenH323 that registers to this Gatekeeper.
I have a Cisco CallManager that registers to this Gatekeeper.
The problems I face are:
1. Calling from Cisco IP Phone to Asterisk.
-- Executing Dial("H323/ip$10.169.208.3:4791/194",
"IAX2/4555564| 20| r") in new stack
-- Called 4555564
-- Call accepted by 82.221.53.53 (format ULAW)
-- Format for call is ULAW
-- IAX2/4555564/1 is ringing
-- Nobody picked up in 20000 ms
-- Hungup 'IAX2/4555564/1'
-- Executing VoiceMail("H323/ip$10.169.208.3:4791/194",
"u4555564") in new stack
If I answer this call with IAX Phone on my Windows Desktop then
audio is not transcoded in Asterisk between codecs.
I can see that both phones are sending Asterisk udp packets but no
packets are sent from Asterisk to neither phones.
Is there not supposed to be a transcoder in Asterisk to transcode
GSM <-> uLaw ?
If I don't pick up the call the VoiceMail answers. I can't
hear anything in my Cisco Phone when voicemail answers.
If I dial VoiceMailMain I will not hear anything in my Cisco IP
Phone either.
2. Calling from Asterisk to Cisco IP Phone.
exten => _45570XX,1,Dial(H323/${EXTEN}) ; With Gatekeeper this
should be the Dial Command, right ?
exten => _45570XX,2,Hangup
-- Executing Dial("IAX2/4555564@4555564/2",
"H323/4557040") in new stack

3. Asterisk does not answer all h.323 calls.
tcpdump of CallManager (10.169.208.3) calling Asterisk
(10.169.208.11) but Asterisk is not answering.
no entries found ? Asterisk log or console to explain why the call
is not answered.

4. Changing Asterisk configuration.
If I change Asterisk configuration and execute the reload command no
H.323 communication will work.
I am forced to stop Asterisk service, clear the endpoint from the
Gatekeeper and restart Asterisk.

Gunnar Gestsson
