Abstract
The ShoreTel system has some known limitations with SIP trunking, please refer to ShoreTel‟s Administration Guide, chapter 18, for the SIP trunking limitations. Some customers may have the need to implement a SIP trunk from an Internet Telephony Service Provider (ITSP) to take advantage of reduced telephony costs, but they require some of the features that aren‟t supported on a ShoreTel system, via SIP trunks. In order for the customer to take advantage of the ITSP‟s offerings and not be affected by ShoreTel SIP trunk limitations they will need to implement an Integrated Access Device (IAD) to convert the SIP signaling to a T1 PRI. In this manner ShoreTel will not have any feature limitations and the customer can still take full advantage of the ITSP‟s offerings.
