Вот и мне не совсем понятно.
Побольше бы debug'a.

Такой же звонок с телефона по SIP:

мало
лог sip между этим надо

Включил лог SIP, сделал звонок - Между этими строками нет ничего от SIP.
Но вот при включенном логе RTP получилось вот что:

связывал * с CCM и по сипу и по h.323 (openh323), без каких-либо проблем
попробуйте через openh323, не получится - кидайте сюда конфиги астера и скрины с CCM

при дебаге chan_ooh323 в консоле информации мало полезной выдаётся...лучше смотреть /var/log/asterisk/h323...

...Вы пытаетесь использовать модуль chan_ooh323, а по его работоспособности много написано и на этом форуме и на других...у меня этот модуль с Alcatel OXO не заработал...у Вас в конфиге стоит faststart=no и h245tunneling=no портобуйте обе стороны перевести в faststart (может быть заработает)....

...попробуйте модуль chan_h323 более стабильный

Насколько я понял из лога:

-- Executing [99502@internal:1] Dial("SCCP/99598-00000006", "OOH323/99502@10.7.130.1:1720") in new stack
--- ooh323_request - data 99502@10.7.130.1:1720 format 0x8 (alaw)
--- ooh323_alloc
== Using ooh323 TOS bits 16
+++ ooh323_alloc
--- find_peer "995"

вы пользуетесь ооh323
Недавно пытался зделать звонок на внешний h323
через канал ooh323 и нашел в исходном коде
грубейшую ошибку может она вас спасет

[root@server ~]# cat /root/rpmbuild/BUILD/asterisk-addons-1.6.1.0/channels/chan_ooh323.c | grep tmp
1 char tmp[256];
2 ast_copy_string(tmp, data, sizeof(data));
3 dest = strchr(tmp, '/');
4 ext = tmp;
5 } else if ((dest = strchr(tmp, '@'))) {
6 ext = tmp;
7 dest = tmp;

в строчке 2 копируется всего только 3 байта (--- find_peer "995") хотя вы в действительности указываете "OOH323/99502@10.7.130.1:1720"

в доке написано

; For dialing into another asterisk peer at a specific exten
; OOH323/exten/peer OR OOH323/exten@ip

для правильной отработки как написано в доке надо поправить строчку 2
с ast_copy_string(tmp, data, sizeof(data));
на ast_copy_string(tmp, data, sizeof(tmp));

inki-sasha: я проверил Вашу теорию - не помогло.
Поведение системы не изменилось.

Пытаюсь поиграться с другим модулем h323

По совету terminal пробовал Open H323 - Теперь гудок слышу в обе стороны, а голоса нет. Похоже RTP не поднимается.

Вот h323.conf:

[general]
port = 1720
bindaddr = 10.4.131.116
disallow=all
allow=gsm
allow=ulaw
allow=alaw

progress_setup = 3
progress_audio = yes
hold=q931only

[995]

host=10.7.130.1
faststart=no
context=internal
