How can we send calls from ip extensions via different Sip trunks in cucm? In other words, Can I send call from different ip numbers range via different sip trunks in cucm?
Let's say you have a Range A and another Range B. Range A IP Phone CSS A will have access to a route pattern partition that points to SIP trunk A while Range B IP Phone CSS B will have access to another route pattern that points to SIP trunk B.
Another way could be to use SLRG. This way you won't have to create multiple RP's. Range A IP Phones will have a DP A pointing to a LRG A which further points to SIP trunk A. You set the same for the Range B IP Phones but the DP/LRG/SIP Trunk will be B in this case.
Thank you so much for your kind response. Is there limitation in number of sip trunks with same ip address with Service provider with different port number.? Can we create as many as sip trunks as we wish with same ip ?
