Hi! I have a problem with my ISP and SIP on my 2811.
My number 2922781 register well, I don't have a problem with incoming calls. But outgoing calls fails. ISP's techsupport sayd that problem with source port in my SIP session. My number register on SIP-server like [email protected]:5060, but outgoing call come from different source port and that's why SIP-server reject call. How can I force use only 5060 port for SIP-session?
