[Serusers] format of entry in user_pref table for value

Hi In the usr_prefrences table for callfwd I need to be able to write sip addresses and pstn numbers. Problemis when I callforward using if (avp_db_load("$ruri/username", "s:callfwd")) { avp_pushto("$ruri/username", "s:callfwd"); append_branch(); route(11); break; }; we get success if the pstn number is entered as 12124234(a)sip.domain and the sip address is entered as iqbal(a)sip.domain However when I look at the Contact header it displays Contact: sip:12124234@sip.domain@sip.domain, sip:12124234@sip.domain@sip.domain. But the calls goes through, similaryly if the forward is to a sip address I get Contact: sip:iqbal@sip.domain@sip.domain, sip:iqbal@sip.domain@sip.domain. Agai with a successful call....now this doesnt seem write even though it works. If I replace avp_pushto("$ruri/username", "s:callfwd"); with avp_pushto("$ruri", "s:callfwd"); then the sip.domain part does not display, and the call fails. I need to store all values with the domain, since I might need to relay a call to a different domain eg fwd.. Whats the best way of doing this... Iqbal
