Description
r377 падает при получении входящего вызова. Сначала на входящий INVITE пульт почему-то отправляет ответ "488 Not Acceptable Here", а затем падает по SIGSEGV:

Оказалось, что PJSIP был собран без поддержки ресэмплинга. Пересобрал с поддержкой ресэмплинга - падения прекратились.
Саша, может имеет смысл описать где-нибудь на wiki-страничке все требования к зависимостям программы? Чтобы там было написано, например, что PJSIP непременно должен быть собран с поддержкой ресэмплинга...
И было бы совсем хорошо, если бы пульт диспетчера при старте сам проверял (если есть такая возможность), имеется ли поддержка ресэмплинга у PJSIP и т.п., и если что-то не так, выдавал бы, как минимум, предупреждение в лог...
Вот сейчас проверил - наличие поддержки ресэмплинга вполне можно проверить с помощью макроса PJMEDIA_RESAMPLE_IMP... Саша, что скажешь?

Про "добавить в вики что-то полезное", я конечно не возражаю. И насчёт "самопроверки", тоже не возражаю, напиши тикет с предложением.
Note:
See TracTickets

Пересобрал PJSIP с отладочной информацией. Вот вывод отладчика:
