<div> Yiasou re. I am doing a similar scenario with CallManager Express. You need to TFTP the phone loads to your SRST gateways flash. Are your phones getting IP addresses from the SRST gateway? or another server local to them? Whatever the case, you need to set up the TFTP template for option 150 and point it to the SRST gateway. At me CCME site, the phones are getting their IP addresses, and TFTP loads from the local CCME router. Let me know if you need config info.
