[Freeswitch-users] mod_voicemail and non-numeric id

Hello list. I've decided to use non-numeric id's at users configuration. <user id="001565229c95" number-alias="109" mailbox="109"> But when the call goes to voicemail app <action application="bridge" data="loopback/app=voicemail:default ${domain_name} ${dialed_extension}"/> switch_ivr_play_say.c:244 Handle say:[001565229c95] (ru:ru) 2012-04-27 11:39:54.452208 [INFO] mod_say_ru.c:721 ru_say!!! 001565229c95! say_opt.gender=0 say_opt.cases=0 2012-04-27 11:39:54.532157 [DEBUG] switch_ivr_play_say.c:1309 Codec Activated L16@16000hz 1 channels 20ms The mod_say pronounces user id. How to force to pronounce number-alias?
