SIP with PSTN vs SRST SIP

Hi monsters of IP Phone

I have a problem with that model:

PSTN---->SIP--->VG----->H323------>CUCM 9.1

The question is when the site stand in SRST Mode, the call can´t go to PSTN, specially when i use this commands in to configure SRST SIP:

bind control source-interface XXX

bind media source-interface  XXX

The phones 69XX using SIP and other models as 79XX use SCCP.

Any ideas?

I discovered another problem, when phones are registered in SRST, the call is answered by CUE voice-gateway, however, when it is forwarded to any extension, the call stays with one way audio

thats the problem
